freebsd stable - Mar 2005 - 4.11 to 5.3 Any issues I should know before making the change.

Just wanted to find out if there are any issues when jumping from the 
4.11 to the 5.3. Like way out of the ordinary type problems, this jump 
for me is going to be very difficult as it is and I want to make sure I 
don't get a surprise...

Read the release errata and errata notes, of course.

Read the UPDATING section on updating from 4-Stable to 5.3. Only update
to 5.3_Release, not Stable. Read the UPDATING section on updating from
4-Stable to 5.3 again. Modify your kernel configuration for V5. (It is
often easier to start with a V5 GENERIC and adjust it to your needs
instead of trying to make all of the changes to your V4
configuration. If in doubt about any option, check /sys/conf/NOTES and
/sys/$ARCH/conf/NOTES. Read the UPDATING section on updating from
4-Stable to 5.3 again.

And, if I didn't already mention it, read the UPDATING section on
updating from 4-Stable to 5.3 again. Reading all of UPDATING is
encouraged, but that's a LONG file in 5.3. If you go to the last 7 or 8%
of the file, you will find the upgrade instructions. These are what is
critical. Don't skip any of the notes, either. I just did one of these
upgrades and I missed one note. It was a serious mistake that took
almost 3 hours to recover from. (This was a remote system. If it had
been local the delay would have been about 45 minutes.)

Read the migration guide that comes with the 5.3 release documentation:

http://www.freebsd.org/releases/5.3R/migration-guide.html

That's what we wrote it for.  :-)
