The only problem I experienced was that BIND 8.2 was much less tolerant of 
syntax errors/typos in the zone files.  [I can't tell if this was a 4.x -> 
8.x change, or if this was an issue with the stock 4.x package that came 
with HP-UX.]  

In any case, watch for the word "rejected" in the logfile, in reference to 
a zone load.  I had a devil of a time tracking this one down, as our 
primary DNS server would load the zone for itself [i.e. we could resolve 
names from the master] but it would refuse to transfer the "bad" zone data 
to the secondaries...

One other quirk: in an interactive "nslookup" session, people complained 
that they could no longer run
    	ls <some domain>
but that was simple to resolve: run
    	ls -d <some domain>
instead.

Save for this, the upgrade was rather quiet and uneventful.  Because the 
zone files don't need to be changed, rolling back the upgrade would take 
just moments.
