Updated: May 13, 2016
Applies To: System Center 2012 SP1 - Data Protection Manager, System Center 2012 - Data Protection Manager, System Center 2012 R2 Data Protection Manager
If your upgrade to System Center 2012 – Data Protection Manager (DPM) does not complete successfully, or if you need to go back to DPM 2010, you can roll back the upgrade without losing the benefit of protection that you previously had.
Backup your DPM database.
If DPM 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, see Uninstalling DPM.
Install System Center 2012 – Data Protection Manager (DPM). If you had any updates installed, reinstall them in the same sequence that you had installed them the first time.
Run the following query on the DPM 2010 database in Administrator mode to find the sequence in which the updates were originally applied.
select * from tbl_DPM_InstalledUpdates
Before you began the upgrade, you should have backed up your DPM database and stored it in a safe location.
To restore the DPM 2010 database to the SQL Server instance that DPM was using previously, open DPM Management Shell and run the command dpmsync –restoredb..
To synchronize the databases, in DPM Management Shell, run the command dpmsync –sync.
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 was functional after installation, any recovery points created will be lost. Recovery points created prior to upgrading will still be available.
