I ran into a problem regarding upgrading from DPM 2010 to DPM 2012 the other day. When performing the upgrade I got the error 832 that would like me to verify that the SQL server was properly installed and running.
To resolve this error and be able to perform your upgrade you must delete the schema named DPMDBReader$To delete the schema open the SQL management studio on the DPM 2010 server do this:
in the original DPM 2010 SQL database and then
perform the upgrade again.
- Open the SQL Management Studio and connect to the DPM instance
- Go to DPMDB
- Delete the DPMDBReader$Machinename schema.
