After you have migrated the cluster port rules, applications, and services from the source cluster to the target cluster, you are ready to enable client access to the applications on the target cluster. Enable client access to the target cluster while maintaining the DNS entries to the source cluster. Over a period of time, remove the DNS entries that point to the source cluster.

Enable client access to the applications on the target cluster by completing the following steps:

  1. Create the appropriate DNS entries for the applications running on the target cluster.

    For more information about how to create DNS entries for your applications see "Managing resource records" in Help and Support Center for Windows Server 2003.

  2. Monitor client traffic to determine if clients are accessing the target cluster.

  3. Over a period of time, such as a few hours or a day, confirm clients accessing target cluster are experiencing normal response times and application responses.

  4. Remove the DNS entries pointing to the source cluster.

    For more information about how to remove DNS entries for your applications see "Managing resource records" in Help and Support Center for Windows Server 2003.

  5. Prevent new clients from accessing the source cluster by performing a drainstop on the source cluster.

    For more information about how to perform a drainstop, see "Create and Manage Network Load Balancing Clusters" in Help and Support Center for Windows Server 2003.

  6. Monitor client traffic to the source cluster to determine when clients are no longer accessing the source cluster.

  7. When clients no longer access the source cluster, decommission the source cluster hardware.
