Yayyyy!

The followup (for anyone interested):

GWIA1 now unloaded and all going through GWIA2.

You think like me.

I will keep the GWIA1, just unloaded as you mentioned.
Can bring back if needed.

Will flip flop MX records once I am satisfied things are working.

The only concern I have noted is that the GWIA2 box is at about 65%
utilization on average.

It is a COMPAQ proliant 933MHZ  box that is also WebAccess.
Seems to me, that should be enough for about 12K SMTP messages per day
and about 30 active WA users.

I will reboot GWIA2 server Friday and see if this utilizaton persists.

Thank you.

Dana

It worked for us a few weeks back. Nary a sniff when the old one went
away. Just to be on the safe side, I left the machine up but gwia down
for a week or so, just for a quick recovery if needed.

We may end up doing it again. Yuk.
