Well, while my skills about FreeBSD is not good enough to let me feel OK to
experiment with 6.2 to 6.4 to 7.2 to 8.0 updating, and while server is hard
to physically access, I guess that just to do fresh install of RELEASE and
re-configuring it in the way that Tim Judd <tajudd at gmail.com> told, would be
much more quick and safe for my services running on this server now.
So the last question is which version (7.2 or 8.0) to choose. Am I right if
I say "there would no problems with hardware compatibility on 8.0 if there
wasn't on 6.2"?
