preparation, and step sections again. Therefore, each system will take its turn at being Site #2 while
the first system being merged to will continue to be Site #1.
The merge process permanently affects a database. Before merging, you create backups of all
wpdomain.db
files for the primary and secondary domains that will be affected by the merge.
This allows you to recover from any mistakes. For more information, see Section 9.4, “Planning the
Location of the Domain Database Backup Directories,” on page 54 .
During the merge, you must shut down any GroupWise Message Transfer Agents (MTAs) that can
write to the domain databases. Even though you shut down the MTAs during the merge, users can
continue to use GroupWise because the Post Office Agents (POAs) do not need to be shut down.
The following GroupWise agent functions are not available until the MTAs are running again:
Š Transferring e-mail messages between post offices
Š
Logging statistics
Š
Updating domain database files
Š
Replicating database information
Š Synchronizing GroupWise with Novell

If Site #2 has a primary domain and some secondary domains, you first release all of the secondary
domains in Site #2 to become primary domains in their own GroupWise systems. Then you merge
each Site #2 primary domain one at a time with the primary domain of Site #1. In other words, you
run the merge process once for each domain in Site #2. For more information, see
Section 11.5,
“Releasing Site #2 Secondary Domains,” on page 71 .
One link (of any type) must exist between a domain in Site #1 and the domain being merged in Site
#2. The merge utility automatically creates indirect links between the Site #1 secondary domains
and the Site #2 domain being merged. You have the option to accept these indirect links and
configure them later (if necessary), or you can create direct links between all domains in Site #1 and
the domain being merged from Site #2 before beginning the merge. All links must be completed and
correct before you run the MTAs after merging the systems. For more information, see
“Linking the
Domains” on page 56 .
WORKSHEET
Under Item 23: GroupWise MTAs for Sites #1 and #2 , list the GroupWise MTAs for both sites that you
need to shut down during the merge.
The items in the worksheet are listed in the order you enter them when running the GroupWise merge
utility. This planning section does not follow the same order as the worksheet, but all worksheet items are
covered.
