Server 2007, s

In general terms, the transition consists of deploying computers running Exchange Server 2007
and then moving storage groups from the computers running Exchange Server 2003 to the new
servers.
How to maintain data protection during a transition to Exchange Server 2007
1. Deploy Exchange Server 2007.
2. Create empty storage groups and databases on the computer running Exchange
Server 2007.
3. Install protection agents on the computers running Exchange Server 2007.
4. Create new protection groups, and add the databases and storage groups that you
created in step 2.
5. Move the mailboxes to the computers running Exchange Server 2007.
6. Remove all storage groups that will be moved to computers running Exchange
Server 2007 from their existing protection groups, selecting the Retain protected data
option.
DPM will retain the associated replica, recovery points, and tapes for the retention range
specified. You can recover data from the recovery points and tapes to a computer
running Exchange Server 2003.
Moving Exchange Servers Between Domains
You cannot do the following for protected computers:
• Change the domain of a protected computer and continue protection without disruption.
• Change the domain of a protected computer and associate the existing replicas and recovery
points with the computer when it is re-protected.
We recommend that you do not change the domain of a protected computer. If you must change
the domain of a protected computer, you must complete two tasks:
• Remove the data sources on the computer from protection while the computer retains its
original domain membership.
• Protect the data source on the computer after it becomes a member of another domain.
To change the domain membership of a protected computer
1. Remove all members from protection groups.
If you retain the replicas and recovery points, the data will remain accessible for
administrative recovery until you delete the replicas. However, it will not be accessible for
end-user recovery.
