I remember that thread and Connie's response. I'm sorry that I suggested in this thread that it was OK; I was confusing RHEL/SL with Fedora, where it is OK and one of the Anaconda pre-release QA tests. I wonder whether preupgrade [1] will available for upgrading from SL6 to SL7; it's not in the repos so it'll probably be an SL7 to SL8 upgrade option (if it's ever adopted by TUV).
