I read most of the answers to this thread and after attempting the
very similar upgrade (6.2-STABLE to 7.3) I can tell you that it can
fail. In fact it did, and several times. In my case there were several
problems I was overlooking, for example I have an IDE drive and 4
satas in a RAID5 config with gvinum. I had completely forgotten I had
moved /usr to the gvinum dirve, so every time I would boot I was
seeing the wrong binaries and libs, and the upgrade process was not
easy. After really screwing up the whole system, I finally resorted to
downloading the iso for v8 cd1 and live. With the help of FixIt the
holographical shell and the live, I was able to recover the complete
system and actually finishing the last steps as I'm writing this. I
mean, I was able to fully recover the system without reformatting and
installing from scratch.

This process taught me several things:

1) upgrade has to be thought out pretty well, examine everything and
plan for contingency. If you have disk arrays they may and should not
mount until the end of the upgrade process IMHO.
2) The upgrade process is not hard at all, once you understand how it
works. You will usually need lots of experience with Unix and hacking
in general.
3) Most importantly, FreeBSD is simply _very hard_ to destroy. I
really, really screwed up my system, and was able to recover it by
using the handbook, google, the install CD and the Live. Now that I
can truly appreciate the separation of system base from everything
else, I can tell you with a lot of certainty that it's really hard not
to be able to recover from a failed upgrade.

Having said all this, make sure that you backup most of what you will
miss, or if you can, backup everything. The upgrade process is not
usually harder than what is stated here:


Also, if your setup is simple enough, you may be able to do it with
the sysinstall utility of CD1, nevertheless, I don t advise it unless
you know what your doing!

Also, in my case I had a _need_ for upgrading, if you don't have a
specific need, just leave it alone. The majority of newer ports will
still work with 6.2. and I don't really think any security things will
affect you if they haven't already!
