XP pre-RC1 upgrade to RC1

[dacris 0]

I just wanna know if it's ok to upgrade an older pre-RC1 build of XP to RC1. I heard that it's not recommended, but how bad can such an upgrade really be?? I don't feel like starting from scratch all over again and I would like to upgrade to the RTM from RC1/2 if possible, not do a clean install again.

It'll work, but as always, YMMV...
