Configuration Summary:
I have a SSIS package that was running fine on SQL2008R2 using Environmental Variables pointing to a configuration file for connection strings.
The ProtectionLevel of the package is set to "DontSaveSensitive".
Issue:
After upgrading to SQL2012, I upgraded the package using VS2010 Shell and left it in package deployment model. When I try and run the package in VS, I am getting the following errors at the first Data Flow Task it reaches:
[OLE DB Destination [2]] Error: SSIS Error Code DTS_E_CANNOTACQUIRECONNECTIONFROMCONNECTIONMANAGER. The AcquireConnection method call to the connection manager "DB_Connection" failed with error code 0xC0202009. There may be error messages posted before this with more information on why the AcquireConnection method call failed.
[SSIS.Pipeline] Error: OLE DB Destination failed the pre-execute phase and returned error code 0xC020801C.
The part that is really throwing me is that earlier in the package, the same "DB_Connection" manager is used successfully in a number of Execute SQL Tasks. So, it seems the connection strings are being read from the configurations correctly.
Any help anyone can give to point me in the right direction will be much appreciated. I would prefer to not have to move to a project deployment model at this time if I do not have to.
