The hardware upgrade was trivial (I just did exactly all this stuff
last Sunday on our office server and workstations.) Make sure you
have the right allen wrench, the biggest nuisance continues to be the
stupid ethernet connector, it tends to fall out, especially from
workstations (cause they move when they're bumped.) If any workstations
won't boot immediately check the connector, I fell for that *again*
tonight, spent an hour doing wizardly things with rarpd and etherfind
and it was the *#$%& connector on the diskless station...ugh!

To do the SUN3.0 upgrade do a full dump (level 0) and proceed as it
says in the manual, I had no troubles. Before you bring down the SUN2.0
write down the size of all your logical partitions (you'll repartition
the disk so knowing what you need will be handy), your diskless and
server node's IP and Ethernet addresses and names, they'll come in handy
when you run 'setup' which is amusing (Macintosh style click-click-mouse
hits Unix installation!) You really only have to commit to the root
partition in diag as you can readjust (with slide bars and the mouse)
the other partitions from mini-unix.

If you don't do regular backups I would back it up twice but I'm
paranoid (and I do regular backups.) A bad tape block could ruin
your day. After you have SUN3.0 up you just do restores and you're
done (well, you get to put back local hacks, recompile etc tho the
old binaries will work in general.)

There are ways around doing the full backup/restores but I just went
for it so I could repartition things better, besides, it let me catch
up on few newsgroups on another system :-)
