Anyone has migrated Xorg from 6.9 to 7.2 with success ?

[Frank Bonnet]

Hello

I tried twice starting from a fresh 6.2-R installed machine
and followed intructions of the updating file but it failed
twice ... Once Xorg has been upgraded I've never been able
to start X server again , I use KDE so I start X server with
the kdm command.

Thanks a lot for any help
