Okay, another question: Since EM 10gR2 (Grid Control) stores all the information inside the target database (AWR), is it worth upgrading and copying the old repository database to the new hardware and database? Or can I just install GC with new database option? What does it contain? Does anyone know?

I want to upgrade the OMS to 10.2.0.1 and move the OMS to a new hardware running the same OS platform and version RHEL3. I am thinking the following upgrade plan should work; 1. Install 10.2.0.1 GC on new hardware. 2. Keep auto discovery off. 3. Export/import data from old database to new database. 4. Turn auto discovery on. 5. Shutdown OMS on old machine and start on the new one. Does this sound reasonable? Has anyone any experience of this sort? Can anyone suggest any documents available that I can refer? -Amit.
