Just to answer my own question, in case anyone was wondering. There's a note on Metalink, that this is not recommended yet. The errors i got were about OLAP not being installed on the target database. They are just warnings that it was trying to import OLAP back in and couldn't. Workaround was specifying the import with parameter version=10.2 Lyall -----Original Message----- From: lyallbarbour@xxxxxxxxxxxxxxx To: oracle-l@xxxxxxxxxxxxx Sent: Thu, Feb 4, 2010 12:38 pm Subject: datadump from 11g R1 to 11g R2 Anyone know if we can do this? i'm getting an error importing into 11g R2 about DBMS_CUBE_EXP Should i do this some other way? Trying out RAT, and i thought this was how i was supposed to do this from reading the docs. Make a test instance, then take a snapshot of the workload... then run it on the refreshed instance. Lyall
