Upgrade Guide for ISA Server 2006 Enterprise Edition

Microsoft® Internet Security and Acceleration (ISA) Server 2006 provides a path for upgrading your ISA Server 2004 computers, from an existing deployment of ISA Server 2004 to a deployment of ISA Server 2006. During the upgrade process, the upgrade mechanism maps the ISA Server 2004 configuration to a valid ISA Server 2006 configuration.

Bb794804.note(en-us,TechNet.10).gifNote:
There is no direct upgrade path from ISA Server 2000 to ISA Server 2006.

This guide includes an overview of the supported upgrade scenarios, upgrade requirements, and upgrade procedures for ISA Server Enterprise Edition. The following topics are covered:

For information about upgrading ISA Server 2004 Standard Edition, see "Upgrading ISA Server 2004 Standard Edition to ISA Server 2006 Standard Edition" at the Microsoft TechNet Web site.

To upgrade to ISA Server 2006 Enterprise Edition, you need:

  • A personal computer with a 733-megahertz (MHz) or faster processor.
  • A Microsoft Windows Server™ 2003 operating system with Service Pack 1 (SP1) or Microsoft Windows Server 2003 R2 operating system.
    Bb794804.note(en-us,TechNet.10).gifNote:
    You cannot install ISA Server 2006 on 64-bit versions of Windows Server 2003 operating systems.
  • 512 megabytes (MB) of physical memory.
  • One local hard disk partition that is formatted with the NTFS file system.
  • 150 MB of available hard disk space. This is exclusive of hard disk space you want to use for caching.
  • One network adapter that is compatible with the computer's operating system, for communication with the Internal network.
  • An additional network adapter for each network connected to the ISA Server computer.
  • ISA Server 2004 Enterprise Edition or ISA Server 2004 Enterprise Edition with Service Pack 2 (SP2) installed.
  • When upgrading, the ISA Server 2006 language must match the currently installed ISA Server 2004 language.

The following features are no longer supported in ISA Server 2006 and need to be uninstalled before upgrading to ISA Server 2006:

  • Firewall Client Share   Firewall Client Share is no longer part of the ISA Server installation. If you need a share point to install Firewall Client, copy the Client directory from the ISA Server 2006 CD to a computer that is not running ISA Server and manually configure the share point.
  • SMTP Message Screener   SMTP Message Screener is not supported by ISA Server 2006.

The following is a list of issues to consider before and after you begin the upgrade process:

  • The ISA Server 2006 Configuration Storage server can only manage ISA Server 2006 arrays. You cannot manage ISA Server 2004 arrays from an ISA Server 2006 Configuration Storage server, and you cannot manage ISA Server 2006 array members from an ISA Server 2004 Configuration Storage server.
  • When you import the ISA Server 2004 configuration, the primary Configuration Storage server is set to the new Configuration Storage server and the alternate Configuration Storage server setting is not upgraded.
  • Log files will be deleted during the upgrade process. ISA Server 2004 log files are not compatible with ISA Server 2006. If you need an archive copy of your log files, see Appendix B: Backup Log and Cache Files.
  • Cache files will be deleted during the upgrade process. To back up your cache files, see Appendix B: Backup Log and Cache Files.
  • In ISA Server 2004, you can configure one virtual IP address through ISA Server Management for each network that is configured for Network Load Balancing (NLB). Additional virtual IP addresses can be defined. However, these additional virtual IP addresses are configured manually on the network adapters of each array member. The ISA Server 2006 upgrade process will only upgrade the virtual IP address for a network that is configured in ISA Server Management in ISA Server 2004, and will delete the additional virtual IP addresses that have been configured on the network adapters. ISA Server 2006 allows you to define multiple virtual IP addresses for a network though ISA Server Management. If more than one virtual IP address has been configured for an ISA Server 2004 NLB-enabled network, you need to reconfigure the additional virtual IP addresses in ISA Server Management, after the upgrade is complete.
  • ISA Server 2004 SP2 HTTP compression settings are not upgraded. Record your HTTP compression settings and reconfigure HTTP compression settings after the upgrade to ISA Server 2006 is complete.
  • When upgrading from ISA Server 2004 Enterprise Edition, the following change to authentication security is implemented. This is the behavior in ISA Server 2004 Enterprise Edition with SP2:
    • When you use HTTP-to-HTTP bridging, ISA Server will not allow traffic on the external HTTP port when the Web listener is configured to request Basic, forms-based, or Remote Authentication Dial-In User Service (RADIUS) authentication. This is a security-related change. These credentials should be encrypted, and not sent in plaintext over HTTP.
  • The ISA Server 2004 Microsoft Management Console (MMC) snap-in can be upgraded to ISA Server 2006 MMC. The ISA Server 2004 and ISA Server 2006 MMC cannot reside on the same computer.
  • DiffServ settings are not upgraded to ISA Server 2006. Record your DiffServ settings and reconfigure DiffServ settings after the upgrade to ISA Server 2006 is complete.
  • For the most recent information, see "ISA Server 2006 Release Notes" at the ISA Server Web site.

The following sections discuss the upgrade methods and supported scenarios for ISA Server 2006 Enterprise Edition.

Configuration Storage Server

The Configuration Storage server stores the configuration information for all of the arrays in the enterprise and therefore needs to be upgraded first.

There is no in-place upgrade available for the Configuration Storage server. To upgrade an ISA Server 2004 Configuration Storage server, you need to export the configuration and import the configuration to a new ISA Server 2006 Configuration Storage server. The new ISA Server 2006 Configuration Storage server can be a new computer. Or, you can uninstall the ISA Server 2004 Configuration Storage server feature and then install the ISA Server 2006 Configuration Storage server feature on the same computer.

Bb794804.note(en-us,TechNet.10).gifImportant:
The ISA Server 2006 Configuration Storage server cannot manage ISA Server 2004 arrays. If you will not be upgrading all of your arrays to ISA Server 2006 at the same time, we recommend that you install the ISA Server 2006 Configuration Storage server on a new computer. This enables you to continue to manage the remaining ISA Server 2004 arrays from the ISA Server 2004 Configuration Storage server and manage the upgraded ISA Server 2006 arrays from the new ISA Server 2006 Configuration Storage server.

Note the following:

  • When you import the ISA Server 2004 configuration, the primary Configuration Storage server is set to the new Configuration Storage server, and the alternate Configuration Storage server setting is not upgraded.
  • If you have a replica Configuration Storage server installed, before starting the upgrade process, make sure that all changes have been replicated between the Configuration Storage servers. For information about checking the replication, see Active Directory® Application Mode (ADAM) product Help.

ISA Server Services

The supported upgrade methods for the ISA Server services are listed in the following table.

Path Description

In-Place Upgrade

With an in-place upgrade, you can upgrade your existing ISA Server 2004 array member to ISA Server 2006 on the existing equipment. The ISA Server 2006 installation process detects a valid version of ISA Server 2004 and performs an upgrade installation.

Migration

With a migration, you can install a new copy of ISA Server 2006 and join the enterprise.

Supported Upgrade Scenarios

The following table lists the upgrade scenarios supported by ISA Server 2006.

Existing version New version Supported or not supported

ISA Server 2004 Standard Edition, ISA Server 2004 Standard Edition with SP1, or

Note the following:

  • In addition to the product upgrade, ISA Server 2006 also supports a build-to-build upgrade. This allows you to upgrade a beta version of ISA Server 2006 to a new build of the same product. The following build-to-build upgrades will be supported:
  • During the upgrade, ISA Server services are not operational. We therefore recommend that you disconnect the ISA Server computer from the External network until the upgrade is complete.

This section describes four scenarios to upgrade ISA Server 2004 Enterprise Edition to ISA Server 2006 Enterprise Edition, while maintaining existing settings and configuration for each scenario:

Scenario One: Single Configuration Storage Server with One Array

Contoso Corporation, a small to medium size organization, wants to upgrade their existing ISA Server 2004 Enterprise Edition deployment to ISA Server 2006 Enterprise Edition. Contoso has deployed ISA Server 2004 Enterprise Edition in the following configuration:

  • There is one Configuration Storage server in the main office.
  • There is one array in the main office, which is named HQ.
  • The HQ array has one array member, which is named ISA_FW01.

The following table provides information about the ISA Server 2004 computers before the upgrade.

Yes

isa_css.contoso.com

ISA Server 2004 Configuration Storage server

This upgrade path enables Contoso to:

  • Make and apply firewall policy changes, even when they are preparing for the upgrade and during the upgrade process.
    Bb794804.note(en-us,TechNet.10).gifNote:
    Any changes made after the ISA Server 2004 configuration has been exported will need to be duplicated on the ISA Server 2006 Configuration Storage server after the configuration has been imported. If there are a large number of changes, the export and import process can be repeated.
  • Move the Configuration Storage server to new equipment.
  • Evaluate how the ISA Server 2004 configuration imports to ISA Server 2006, without affecting the production computers.

Scenario Three: Single Configuration Storage Server with Multiple Arrays

Contoso Corporation, a medium to enterprise size organization, wants to upgrade their existing ISA Server 2004 Enterprise Edition deployment to ISA Server 2006 Enterprise Edition. Contoso has three regional offices that are connected using leased lines. Contoso deployed ISA Server 2004 Enterprise Edition for its ability to centrally manage their entire ISA Server deployment from their main office.

Contoso has deployed ISA Server 2004 Enterprise Edition in the following configuration:

  • There is a single Configuration Storage server located in the New York office.
  • There is one array each in New York, Hong Kong, and London. These arrays are named NY, HKG, and LON.
  • Each array has a single array member.

Contoso wants to upgrade to ISA Server 2006 but cannot upgrade all of the arrays at the same time. Because ISA Server 2006 can only manage ISA Server 2006 arrays, Contoso needs to manage both ISA Server 2004 and ISA Server 2006 deployments until all of the arrays are upgraded to ISA Server 2006. Contoso will upgrade the Configuration Storage server along with the array in New York first. Then the London array will be upgraded, followed by the Hong Kong array. After the last array is upgraded, the ISA Server 2004 computer can be taken out of service.

The following table provides information about the ISA Server 2004 computers before the upgrade.

Scenario Four: Load Balanced Array

There are two mechanisms for load balancing array traffic between array members:

  • DNS round robin   For each array member's IP address, there is a unique Domain Name System (DNS) entry for the array. When providing an IP address lookup for the array's DNS name, the DNS server cycles between the different array members' IP addresses.
  • Network Load Balancing (NLB)   The array is configured with a virtual IP address to which all array members receive requests and determine which array member will answer the request.

This section explains how to properly upgrade an array with DNS round robin or NLB.

Note the following:

  • In ISA Server 2004, you can configure only one virtual IP address for each network that is configured for Network Load Balancing (NLB) through ISA Server Management. Additional virtual IP addresses can be defined. However, these additional virtual IP addresses are configured manually on the network adapters of each array member. The ISA Server 2006 upgrade process will only upgrade the virtual IP address for a network that is configured in ISA Server Management in ISA Server 2004, and will delete the additional virtual IP addresses that have been configured on the network adapters. ISA Server 2006 allows you to define multiple virtual IP addresses for a network though ISA Server Management. If more than one virtual IP address has been configured for an ISA Server 2004 NLB-enabled network, you need to reconfigure the additional virtual IP addresses in ISA Server Management, after the upgrade is complete.
  • If you have configured both DNS round robin and NLB for an array, you need to disable one method before upgrading, perform the upgrade, and then reinstitute the disabled load balancing method.

DNS Round Robin

Perform the following procedure to upgrade an array that is load balanced with DNS round robin. This procedure enables the array to continue to provide services to your users during the upgrade process.

Bb794804.note(en-us,TechNet.10).gifNote:
The assumption is that the Configuration Storage server has already been successfully upgraded.

Perform the following procedure on each array member.

To upgrade an array that is load balanced using DNS round robin
  1. Remove the array member's IP address from the array's DNS entry. This will stop new requests from being forwarded to this array member, but does not have any effect on existing connections to the array member.

    Bb794804.note(en-us,TechNet.10).gifNote:
    Depending on the Time to Live (TTL) of the entry on the DNS server, clients and other DNS servers will cache the existing array member's IP address until the defined TTL has expired, which might result in new connections that will be sent to that IP address. You can reduce the TTL value for the array's DNS entries to reduce the client cache delay.
  2. Perform an in-place upgrade from ISA Server 2004 to ISA Server 2006. For the procedures to perform an in-place upgrade, see Upgrade the array member in the Single Configuration Storage Server with One Array scenario.

  3. Return the array member's IP address to the array's DNS entry.

  4. Perform steps 1 through 3 for each of the remaining array members.

Network Load Balancing

Perform the following procedure to upgrade an array that is load balanced through NLB. This procedure enables the array to continue to provide services to your users during the upgrade process.

Note the following:

  • The assumption is that the Configuration Storage server has already been successfully upgraded.
    Bb794804.note(en-us,TechNet.10).gifImportant:
    After you complete the upgrade of the Configuration Storage server, you need to disable NLB integration for the ISA Server 2006 array.
  • To avoid disruptions in virtual private network (VPN) site-to-site tunnels, we recommend that VPN tunnel owners be upgraded last in the arrays.
Drain and stop NLB services on the specific array member

To remove the array member from the NLB algorithm, we recommend that you drain and stop the NLB services for the specific array member. This ensures that for all future connections, the array member will no longer be included in the NLB algorithm. Existing connections are not affected by this procedure.

Perform the following procedure on the Configuration Storage server.

To drain and stop NLB services
  1. In the console tree of ISA Server Management, select Microsoft Internet Security and Acceleration Server 2004.

  2. Expand Arrays, and expand the selected array.

  3. Select Monitoring, and in the details pane, click the Services tab.

  4. Select Network Load Balancing for the specific array member.

  5. On the Tasks tab, click Drain and Stop Selected Service to stop the selected service.

Suspend the NLB service on the specific array member

When the NLB services are suspended, existing connections are disconnected. Users can reconnect using the virtual IP address and connect to another array member. When the NLB service on a specific array member is suspended, NLB will not start, even after the server has been restarted.

Perform the following procedure on the Configuration Storage server.

To suspend the NLB service
  1. In the console tree of ISA Server Management, select Microsoft Internet Security and Acceleration Server 2004.

  2. Expand Arrays, and expand the selected array.

  3. Select Monitoring and in the details pane, click the Services tab.

  4. Select Network Load Balancing for the specific array member.

  5. On the Tasks tab, click Suspend Selected Service.

Perform in-place upgrade on the specific array member

Perform an in-place upgrade from ISA Server 2004 to ISA Server 2006. For the procedures to perform an in-place upgrade, see Upgrade the array member in the Single Configuration Storage Server with One Array scenario.

Bb794804.note(en-us,TechNet.10).gifNote:
Because NLB is disabled for the ISA Server 2006 array, the array member will not receive any NLB traffic after the in-place upgrade is complete.
Repeat until half of the array members have been upgraded

Repeat the following until half of the array members have been upgraded:

  • Drain and stop NLB services on the specific array member.
  • Suspend the NLB service on the specific array member.
  • Perform an in-place upgrade on the specific array member.
Suspend the NLB service on the remaining ISA Server 2004 array members

After half of the array members have been upgraded to ISA Server 2006, suspend the NLB service on the remaining ISA Server 2004 array members.

Bb794804.note(en-us,TechNet.10).gifNote:
At this point, NLB service is suspended on both the ISA Server 2004 and ISA Server 2006 array members.
Start the NLB service on the ISA Server 2006 array members

Start the NLB service on the ISA Server 2006 array members. At this point, new connections will be handled by the ISA Server 2006 array members.

Perform an in-place upgrade on the remaining ISA Server 2004 array members

Perform the following procedure on the remaining ISA Server 2004 array members.

To perform an in-place upgrade on the remaining array members
  1. Perform an in-place upgrade from ISA Server 2004 to ISA Server 2006. For the procedures to perform an in-place upgrade, see Upgrade the array member in the Single Configuration Storage Server with One Array scenario.

  2. Enable NLB on the upgraded array member.

To upgrade an array member to new equipment instead of performing an in-place upgrade, use the procedures described in the following sections. When the ISA Server 2004 configuration is imported to ISA Server 2006, the array secrets are also upgraded. Until an ISA Server 2004 array member is upgraded, no new servers can join the array. The following procedures explain how to allow a new server to join an ISA Server 2006 array.

Export (Back Up) the Configuration of the Existing ISA Server 2004 Configuration Storage Server

Perform the following procedure on the ISA Server 2004 Configuration Storage server.

To export the ISA Server 2004 configuration to a file

    Bb794804.note(en-us,TechNet.10).gifNote:
    After an array member has been deleted from the array, an in-place upgrade cannot be performed on the array member to upgrade to ISA Server 2006.

During the upgrade process, existing log and cache files are erased. ISA Server 2004 log files are not compatible with ISA Server 2006. However, ISA Server 2004 cache files are compatible with ISA Server 2006.

Log Files

To back up ISA Server 2004 log files, copy the files to an alternate location. The default location for log files is C:\Program Files\Microsoft ISA Server\ISALogs.

MSDE Log Format

Microsoft SQL Server™ Desktop Engine (MSDE) is installed and configured as the default log storage format. You must first detach the database from the current server and then copy the files to an alternate location.

To detach a database from the server, enter the following lines at a command prompt.

To detach an MSDE database from a server, enter the following
  1. OSQL -S computer_name\MSFW -E

  2. sp_detach_db database_name

  3. go

  4. quit

    Bb794804.note(en-us,TechNet.10).gifNote:
    database_name is the name of the .mdf and .ldf files without their extensions.

Now you can copy the .mdf and .ldf files to another location.

To reattach the database to the server, perform the following procedure.

To reattach a MSDE database to a server, enter the following
  1. OSQL -S computer_name\MSFW -E
