During migration, many organizations have a period of interoperability, or "coexistence," between the servers that are running the Exchange 2000 and Novell GroupWise messaging systems because only small organizations can migrate every user in a single night. Therefore, before most GroupWise migrations, organizations establish coexistence so that Exchange 2000 and GroupWise users can continue to communicate and collaborate with one another during the migration, regardless of which messaging system they are on. This article describes the process of migration from Novell GroupWise to Exchange 2000.
During the coexistence period, Exchange 2000 users can see GroupWise distribution lists in the Exchange Global Address List. When an Exchange 2000 user sends a message to a GroupWise distribution list, only one copy of the message is sent over the GroupWise connector. If you activate distribution list expansion, GroupWise can deliver the message to all distribution list members. The following procedure describes the steps you must take to activate distribution list expansion on the GroupWise system.
Both GroupWise API Gateway NLM and GroupWise Patch 2 for API NLM/OS2, with installation instructions, are available from Novell. For more information, visit the Novell Web site Novell Support and Downloads
