Migration process
The ISA Server 2004 Migration Tool enables a full upgrade path for ISA Server 2000 users to ISA Server 2004. Most ISA Server 2000 configuration information will be upgraded to ISA Server 2004. ISA Server 2004 introduces many new features and changes over ISA Server 2000. These changes affect the server configuration and upgrade scenarios.
There are three options for upgrading from ISA Server 2000:
- In-place upgrade.
- In this scenario, you install ISA Server 2004 on the same computer running ISA Server 2000. The configuration is migrated directly to ISA Server 2004, as described in the following topics. You do not have to run any tool.
- Migrate ISA Server 2000 configuration.
- In this scenario, you either install ISA Server 2004 on a different computer, or completely remove ISA Server 2000 before installing ISA Server 2004. In either case, you must use the Migration Tool to migrate the configuration information to ISA Server 2004, as described in the following topics.
- Migrate Routing and Remote Access configuration.
- In this scenario, you may have previously configured virtual private networking using Routing and Remote Access. You can use the Migration Tool to copy some of that configuration to ISA Server 2004, as described in Routing and Remote Access configuration.
In-place upgrade
You can also perform an in-place upgrade by running the Migration Tool on a computer with ISA Server 2000 installed. When you perform an in-place upgrade, ISA Server 2000 is removed and ISA Server 2004 is installed with the migrated configuration.
If you perform an in-place upgrade, ISA Server Service Pack 1 (SP1) must be installed on the computer.
Migrating the configuration
The migration from ISA Server 2000 to ISA Server 2004 includes the following steps:
- Run the ISA Server Migration Wizard on the ISA Server 2000 computer. The wizard creates an .xml file with the configuration information.
- Install Microsoft ISA Server 2004.
- Import the .xml file to the ISA Server 2004 computer. Before you import the .xml file, we recommend that you perform a full backup of the current settings on the ISA Server 2004 computer.
The actual IP address of the external network adapter on the original ISA Server 2000 computer is saved in the .xml file with the configuration information. If ISA Server 2004 is installed on a different computer, you must correct the IP address after you import the .xml file.
What is not upgraded
The following ISA Server 2000 objects and configuration settings are not migrated to ISA Server 2004:
- Bandwidth rules are no longer supported in ISA Server 2004.
- Permission settings, such as system access control lists (SACLs), are not upgraded. For more information, see Administration and monitoring configuration.
- Logging and reporting configuration and information are not migrated. For more information, see Administration and monitoring configuration.
Note that ISA Server 2004 does not install the Firewall Client Share by default.
