Rolling Back a DPM 2010 Upgrade
Updated: May 28, 2010
Applies To: System Center Data Protection Manager 2010
If your upgrade to System Center Data Protection Manager (DPM) 2010 does not complete successfully, or if you need to go back to DPM 2007 SP1, you can roll back the upgrade without losing the benefit of protection that you previously had.
To roll back a DPM 2010 upgrade
If DPM 2010 is installed, uninstall it while retaining your data by clicking Retain disk-based recovery points on the Uninstallation Options page. For step-by-step instructions for uninstalling DPM 2010, see Uninstalling DPM 2010.
Install DPM 2007 SP1. If you had any hotfixes installed on DPM 2007, install those too. For the latest updates and hotfixes for DPM, see Downloads for System Center Data Protection Manager (http://go.microsoft.com/fwlink/?LinkId=188865).
Before you began the upgrade, you should have backed up your DPM 2007 database and stored it in a safe location according to the upgrade instructions provided at Upgrading to DPM 2010 from DPM 2007.
To restore the DPM 2007 database to the SQL Server 2005 instance that DPM was using previously, open DPM Management Shell and run the command
dpmsync –restoredb. For more information about dpmsync, in the DPM 2010 Operations Guide, see Using DPMSync (http://go.microsoft.com/fwlink/?LinkId=196929).
To synchronize the databases, in DPM Management Shell, run the command
Open DPM Administrator Console and ensure that all agents are the same version as the DPM server.
Perform a consistency check on all the data sources.
|If DPM 2010 was functional after installation, any recovery points created by using DPM 2010 will be lost. Recovery points created prior to upgrading to DPM 2010 will still be available.|
