Upgrading from xfree to xorg, any major issues?

[Chris Green]

Some time soon I'm going to have to upgrade my present Cygwin/X
installation which is mostly 4.3.0.x Xfree to the latest Xorg
versions.

How painless is this likely to be?  I run Cygwin/X on a Win2k machine
and use it to display my Slackware Linux desktop using xdm.
