Part of the 12c upgrade.

As for migrating to 11g, I simply can't recall that now - those brain cells are long gone. However, if the upgrade path was a single repository then it should definitely have kept your history. If not then I think you were on your own.

Of course, the obvious answer is to can your upgrade to 11g project and so straight to 12c. ;)

That's doable from the latest 10g release (10.2.0.5) or directly from 11g of course.

>> 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.
