The most common advice is to upgrade incrementally. Upgrading directly
from 4.0 to 4.8 is likely to encounter problems. 

I personally would recommend 4.0 to 4.3, then 4.3 to 4.6.2, then 4.6.2
to 4.8. Check the handbook for the appropriate CVS tags.

In any case, it is *very* important that you read /usr/src/UPDATING each
time you update your source. This will inform you of any special steps
you need to take before upgrading to that respective version.

If you're especially paranoid and have plenty of time, you could even do
the upgraded in more increments than I recommended. Just be sure to read
the UPDATING file each time.

Hope that helps,
Adam
