Verifying Application Compatibility with IIS 6.0 Worker Process Isolation Mode in a Lab

Applies To: Windows Server 2003, Windows Server 2003 with SP1

After modifying your Web sites, applications, setup programs, and provisioning scripts to be compatible with worker process isolation mode, you need to test your modifications in a lab. Be sure to test for compatibility before performing the migration process on a production Web server.

Verify the compatibility of your Web sites, applications, setup programs, and provisioning scripts with worker process isolation mode in a lab by completing the following steps:

  1. Make an image backup of the source server.

  2. Restore the backup to a Web server in your lab, referred to hereafter as a test source server. Ensure that the test source server is not connected to your production network, to prevent any problems encountered during the migration from affecting your production network.

  3. Perform a migration from the test source server to the test target server.

  4. Configure the test target server to run in worker processor isolation mode or IIS 5.0 isolation mode.

  5. Make the necessary modifications to the Web sites, applications, setup programs, and provisioning scripts so that they are compatible with worker process isolation mode.

  6. Verify that the Web sites, applications, setup programs, and provisioning scripts run correctly on the test target server.
