Verifying Application Compatibility with 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 upgrade 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 Web server you are going to upgrade.

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

  3. Perform an upgrade on the test Web server.

  4. Configure the Web server to run in worker processor 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 the Web sites, applications, setup programs, and provisioning scripts run correctly on the test Web server.
