Re: Upgrading to Exchange 2003 - but not the Front Ends firs |
|
|
Guess no one was sure what to do here - no replies...
Here is what I did and couple of lessons learned...
I made my 2nd (Exchange 2000) FE a BE (took the checkbox off) - OWA stopped
working because of authentication was different (was doing anonymous &
integrated - with SSL). But, I was able than to start Exchange 2003 install
on OWA1. Than I made OWA2 a FE again! OWA started working and I was able to
build my new one... I wasn't able to do SP1 (again telling me that I have
2000 FE), so now it works for all Exchange 2000 users but not for Exchange
2003 (BEs are SP1)...
I'm rebuilding the OWA2 as 2003 now, after I make it FE and put into
production I will SP1 one than the there and they should work fine for both
E2K and E2K3 users...

2003 - by installing the two (clustered) NEW Exchange 2003 servers -
without first upgrading my two Front End OWA servers! Microsoft does not
believe I never got a warning that I have to upgrade FEs first!!!
So now (a month later) I get to upgrading my OWA FEs. I blow away one
(they are hardware load balanced so everyone one is using OWA going trough
the other one) and rebuild it to Win2K3 SP1, patched and all join domain,
start exchange 2003 load - get the warning now - can't install another
2003 server till I upgrade the (other) OWA FE!
Now what!? I have to take the downtime ...
Either to uninstall Exchange from the other OWA - than install Exchange on
this one - or -
Can I just make the second OWA a Back END!?!? It will still proxy users to
their Back End (every Back End does that)?! It will probably require me to
reboot - it will start all the services that are not running now (IS) and
be just another 2000 Back End... What do you think?
Thanks!
