related differences between a UE2 and a UE450?
Yeah, it has lockable castors, so you can roll it in.Quote:> all database devices are on a raid cabinet. heres the plan:

Check its dimensions. Sun always does something stupid
with their systems. In the case of the 450 its its length.

You would be better off leaving the old alone. You may needQuote:> 4. Remove sybase from the startup scripts on old, then shutdown

Good luck. You may need it.Quote:> 7. Start Sybase

UE450 from scratch. Attach the RAID device and its controller,
reconfigure & reboot and see what it comes up as. If the
controller id is the same you're in luck. If not, its a bit
Install Sybase on the new box or copy the directory over.
Edit the interfaces file to show the new IP address (if you
copied the IP address of the old machine, make sure you change
its one first and reboot). Run the Sybase start script. If
the controller ID has changed, edit the run script to point
to the new master device and run it with the "-m" option
(i.e. master only). Then change all the sysdevices entries
to suit, shutdown and restart it without -m. Check each of
the databases and make sure you do db dumps before you do
any of the above. When you're done, upgrade the UE2.
