Before you start the migration process, both the Novell® GroupWise® system and the Microsoft Exchange system should be running smoothly. The migration process is performed in three stages. First, the Migration Utility helps you gather important information about your Exchange and GroupWise systems. Second, the Migration Utility helps you plan how you want the Exchange users, distribution lists/groups, and public folders to be organized in your GroupWise system. Third, the Migration Utility performs the migration to GroupWise.
