RE: Oracle Grid... ahem Cloud Control 12c

>> That means you have both running, pre-12c and 12c, each with its own agents. As you move the pre-12c agents, you can sync the history as part of the move to the 12c repository.

Sync'ing the history - is that a 12c feature or is that available in 11g as well? I am in the process of upgrading a Production Grid environment from 10.2 to 11.2. Preserving the history would be great.

Sorry, at the Australian 12c launch, so I just saw this. If you were doing a one system upgrade, you will be upgrading your existing repository, so that keeps everything you had. If you are doing a two system upgrade, you clone the existing repository, leaving the old version with pre-12c agents pointing to it. You can then gradually install 12c agents pointing to the new repository. That means you have both running, pre-12c and 12c, each with its own agents. As you move the pre-12c agents, you can sync the history as part of the move to the 12c repository. Pete

With the EM upgrade, when we re-register the targets do we loose the history of the metrics gathered? Is there a way to preserve the performance metrics history?

Of course, a clean installation does give you the chance to get rid of a lot of old baggage that you may no longer need, but in general this is more of a business decision than a technical one really.
