Okay, Trying to figure out the version compatibility matrix. After two days of chewing on my whole migration issue for my current environment, it looks like I will be creating and setting up Grid control using 11g. I will be upgrading my 9i 32bit databases to 10gr2 64bit. As part of this, I want to get RMAN setup and scheduled backups going within Grid control. But, the question is, when I run RMAN from the Grid control, and the target is a 10g databasd, which rman gets run? The 11g or the 10g? Can rman from 11g be used to backup and restore a 10gr2 database ? Thanks Bob
