Enabling Client Access After Migration

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

After you have migrated your Web sites from the source server to the target server, you are ready to enable client access to the Web sites on the target server, while maintaining the DNS entries to the source servers. After a period of time that meets your business needs, you can remove the DNS entries that point to the Web sites on the source server.

Figure 7.10 illustrates the final step of the process for migrating Web sites from Apache to IIS 6.0.

Enable client access to the Web sites on the target server by completing the following steps:

  1. Create the appropriate DNS entries for the Web sites and applications running on the target server.

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

  2. Monitor client traffic to determine whether clients are successfully accessing the target server.

    For more information about how to monitor client traffic to Web sites on the target server, see Monitor Active Web and FTP Connections.

  3. Establish a monitoring period, such as a few hours or a day, to confirm that clients accessing Web sites on the target server are experiencing response times and application responses that meet or exceed your requirements.

  4. Remove the DNS entries pointing to the Web sites and applications on the source server.

    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. Monitor client traffic to the Web sites on the source server to determine when clients are no longer accessing the source server.

    For more information about how to monitor client traffic to Web sites on the source server, see Monitor Active Web and FTP Connections.

  6. When clients are no longer accessing the Web sites on the source server, decommission the hardware for the source server.
