   Until all arrays are upgraded to ISA Server 2006, you need to manage both ISA Server 2004 and ISA Server 2006 enterprises.

ISA Server 2006 cannot import an exported configuration of an individual ISA Server 2004 array. ISA Server 2006 can only import an exported configuration from ISA Server 2004 when the export was done at the root of the enterprise, which shows Microsoft Internet and Acceleration Server 2004. However, you can import an individual array configuration from one ISA Server 2006 deployment to another ISA Server 2006 deployment. In this procedure, you create a temporary ISA Server 2006 Configuration Storage server and import a single array configuration. After the procedure is complete, the temporary ISA Server 2006 Configuration Storage server is no longer needed.

To enable you to import an individual array configuration from an ISA Server 2004 deployment, the following procedures need to be followed:

• Export (back up) the configuration of the existing ISA Server 2004 Configuration Storage server
  
• Create a temporary ISA Server 2006 Configuration Storage server
  
• Import the exported configuration to NY_CSS_Temp
  
• Export LON array configuration
  
• Import the exported array configuration to NY_CSS06
  
• Upgrade LON array member
  

Upgrade LON array member

In this procedure, you will perform an in-place upgrade from ISA Server 2004 to ISA Server 2006, on the LON array.

Important:
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 process, existing log and cache files will be 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. For more information, see Appendix B: Backup Log and Cache Files.
  
• 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 MOM agent, use ISA Server files and may interfere with ISA Server setup and removal. To avoid issues, stop these applications before running Setup.
  

Perform the following procedure on NY_ISA01.

To upgrade an array member

1. Run ISA Server 2006 Setup. The Setup program detects an existing valid version of ISA Server 2004 Enterprise Edition and performs the upgrade.

2. Insert the ISA Server 2006 Enterprise Edition CD into the CD drive, or run ISAAutorun.exe from the shared network drive.

3. In Microsoft ISA Server Setup, click Install ISA Server 2006 and use the wizard to upgrade to ISA Server 2006 as outlined in the following table.

Page	Field or property	Setting

Complete these steps for the HKG array when you are ready to upgrade the HKG array.

After the last array is successfully upgraded, you can remove NY_CSS_TEMP from service.

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.

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.

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.

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 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.

Note:
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 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.
  

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.

Note:
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. At this point, new connections will be handled by the ISA Server 2006 array members.

Perform the following procedure on the remaining ISA Server 2004 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.
