You can change which domain is primary if it becomes more convenient to administer the primary domain from a different location. You can, however, have only one primary domain at a time. When you convert a secondary domain to primary, the old primary domain becomes a secondary domain.
To convert a secondary domain to primary:
In ConsoleOne, connect to the primary domain, as described in Connecting to a Domain.
Make sure there are no pending operations for the current primary domain. See Pending Operations.
In ConsoleOne, browse to and select the secondary domain you want to convert.
Click Tools > GroupWise Utilities > System Maintenance.
Click Convert Secondary to Primary.
Enter the path to the secondary domain database, then click OK.
The GroupWise View in ConsoleOne displays the primary domain with a red underscore.
