Upgrade Guide for ISA Server 2006 Standard 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 transfers the ISA Server 2004 configuration to a valid ISA Server 2006 configuration.

Bb794775.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 Standard Edition. The following topics are covered:

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

To upgrade to ISA Server 2006 Standard 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 a Microsoft Windows Server 2003 R2 operating system.
    Bb794775.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 Standard Edition, ISA Server 2004 Standard Edition with Service Pack 1 (SP1), or ISA Server 2004 Standard Edition with Service Pack 2 (SP2) installed.
  • When upgrading, the ISA Server 2006 language must match the 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:

  • 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 Back Up ISA Server 2004 Log and Cache Files.
  • Cache files will be deleted during the upgrade process. To back up your cache files, see Back Up ISA Server 2004 Log and Cache Files.
  • ISA Server 2004 SP2 HTTP compression settings are not properly upgraded. Record your HTTP compression settings and reconfigure HTTP compression settings after the upgrade to ISA Server 2006 is complete.
  • 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.
  • When upgrading from ISA Server 2004 Standard Edition, the following change to authentication security is implemented:
    • 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.
  • Firewall logging and Web proxy logging for Microsoft SQL Server™ database settings are not upgraded. Log settings revert to the Microsoft SQL Server Desktop Engine (MSDE) database. Record your SQL Server database settings and reconfigure your Firewall and Web proxy log settings after the upgrade to ISA Server 2006 is complete.
  • For the most recent information, see the "ISA Server 2006 Release Notes" at the ISA Server Web site.

ISA Server 2006 supports the following upgrade paths.

Path Description

In-Place Upgrade

With an in-place upgrade, you can upgrade your existing ISA Server 2004 computer 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 export your existing ISA Server 2004 configuration to a computer with a clean installation of ISA Server 2006.

Supported In-Place Upgrade Scenarios

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

In-Place Upgrade

With an in-place upgrade, you can upgrade your existing ISA Server 2004 computer 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.

This section provides step-by-step instructions about how to perform an in-place upgrade to ISA Server 2006 Standard Edition:

Back Up the Existing ISA Server 2004 Configuration

Bb794775.note(en-us,TechNet.10).gifImportant:
We recommend that you back up your configuration, log files, and cache files before making any major changes to ISA Server 2004. This enables you to restore to your current configuration and import the exported configuration file if there is a problem with the upgrade.

The following procedure describes how to back up your ISA Server 2004 computer. Perform the following procedure on your existing ISA Server 2004 computer.

To back up your ISA Server 2004 configuration
  1. In the console tree of ISA Server Management, expand Microsoft Internet Security and Acceleration Server 2004, and then click Server_Name.

  2. On the Tasks tab, click Backup this ISA Server Configuration.

  3. In Save in, specify the folder in which the export file will be saved.

  4. In File name, type a name for the exported file, and then click Backup.

  5. In Password and Confirm password, type a password that will be required.

Back Up ISA Server 2004 Log and Cache Files

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

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

Bb794775.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 an MSDE database to a server, type the following
  1. OSQL -S computer_name\MSFW -E

  2. sp_attach_dbs @dbname='database_name', @filename1='full_path_to_mdf_file', @filename2='full_path_to_ldf_file'

  3. go

  4. quit

Microsoft SQL Server log format

For instructions about how to back up a database in SQL Server, see the SQL Server product documentation.

File log format

To back up ISA Server log files that are configured in file format, copy the files to an alternate location. The default location for log files is C:\Program Files\Microsoft ISA Server\ISALogs.

Cache files

To back up ISA Server 2004 cache files, copy the files to an alternate location. The default location for cache files is <cache drive>\urlcache.

Run ISA Server 2006 Setup

When you run the ISA Server 2006 Setup program, it detects an existing valid version of ISA Server 2004 Standard Edition and performs the upgrade.

Bb794775.note(en-us,TechNet.10).gifImportant:
If SMTP Message Screener or Firewall Client Share is currently installed, it must be uninstalled before upgrading, because these components are no longer supported in ISA Server 2006.

Note the following:

  • 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.
  • During the upgrade, ISA Server services are not operational and users will experience an interruption of services until the upgrade is complete. We recommend that you notify users before the upgrade that ISA Server services will be unavailable during the upgrade process.
  • Monitoring applications, such as Microsoft Operations Manager (MOM) agent, use ISA Server files and may interfere with ISA Server setup and removal. To avoid issues, stop these applications before running Setup.

The following procedure describes how to run ISA Server 2006 Setup. Perform the following procedure on the existing ISA Server 2004 computer.

To run ISA Server 2006 Setup
