ISA Server 2006 Enterprise Edition supports the following upgrade paths from ISA Server 2004 Enterprise Edition:

  • In-Place Upgrade. With an in-place upgrade, you can upgrade your existing ISA Server 2004 computer to ISA Server 2006 on the existing array 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.

An in-place upgrade requires these steps:

  • Export the configuration from the root node.
  • Uninstall the ISA Server 2004 Configuration Storage servers.
  • Install the ISA Server 2006 Configuration Storage servers.
  • Import the configuration to the new Configuration Storage servers.
  • Perform an in-place upgrade of array members.

Migration requires these steps:

  • Export the configuration from the root node.
  • Uninstall the ISA Server 2004 Configuration Storage servers.
  • Uninstall ISA Server from the arrays.
  • Install the ISA Server 2006 Configuration Storage servers.
  • Install ISA Server 2006 on the firewall arrays (keep the same array and server names).
  • Import the configuration to the new Configuration Storage servers.

Upgrade from ISA Server 2000 to ISA Server 2006 is not supported.
