I'm quite sure Steve has as much info as you, if not less…

The SR will let you know before almost anybody else what's the status there. Until they can give you a workaround, a patch, or something allowing you to perform your in-place upgrade, they will keep working (I imagine the SR will stay open till it get a resolution).

At that time, there will probably be a MOS document explaining the issue and the solution, linking to the required patch if any, or what other workaround should be performed. But you should also get that same info given in your SR.

Right now, keep following your SR, that's where you will get updates (before anyone else) directly.
