Migrating server and agents from DPM 2010 to DPM 2012

Before DPM Server installation, make sure, that your Time Zone is correct. To change Time Zone after DPM installation, follow the instructions (http://technet.microsoft.com/en-us/library/hh758055.aspx):

1. Change Time Zone on Windows Server
2. net stop msdpm
3. DPM Console – Options, Auto Discovery. Change the schedule (this triggers the recalculation of time zones on all jobs)

For server migration, install a new server with Windows Server 2008 R2 and DPM Server 2012 (currently I’m having problem with Windows Server 2012, restore operation is unavailable).

For client migration (use the following steps in this sequence):

1. Stop dpm agent on client machine (net stop dpmra)
2. Uninstall dpm agent from client machine using appwiz.cpl (Add/Remove Programs) or by command line (usable on Core Editions):
   Windows 2008
   MsiExec.exe /X{5EB850FE-84F7-4856-A203-0F80BC93C66A}
   Windows 2003
   MsiExec.exe /X{3EC7C770-9F3F-4177-A754-EBFF04A1AFF2}
3. Remove Protection Group from old DPM Server (you probably will retain the data, since new data is not yet available)
4. Disable firewall on client machine
5. Uninstall agent from old DPM Server and remember those things:
   1. don’t install the new agent before this step
   2. the uninstall will throw error message because we already removed it, this is ok, if the agent disappears from Agents list on DPM Server
   3. please remove client manually and stop the service before the manual uninstall, this way you can avoid the restart of client machine
6. Install the agent from new DPM Server
7. Enable the firewall on client machine (if it was disabled in step 4)
8. Create new Protection Groups and enjoy the game
