Albert,
First thank you very much for your help. Second, your advice has
scared the bejeebus out of me. I understand what you said about
accretion and consolidating everything into one Exch 2003 server, but
that's just way biting off way more than I could chew. Doing that
would mean doing Exch 2003 + RIM BES at the same time which is
something I'm not sure I can pull off.
While going through the documentation to install the first Exch 2003
server, I noticed that domainprep wants to install on basically every
domain that is there.
-----------------------------------------------------------------
http://technet.microsoft.com/en-us/library/aa997526.aspx
You must run DomainPrep in the following domains
* The root domain.
* All domains that will contain Exchange 2003 servers.
* All domains that will contain Exchange Server 2003 mailbox-enabled
objects (such as users and groups), even if no Exchange servers will
be installed in these domains.
* All domains that contain global catalog servers that Exchange
directory access components may potentially use.
* All domains that will contain Exchange 2003 users and groups that
you will use to manage your Exchange 2003 organization.
-----------------------------------------------------------------
It will be very difficult to run domainprep on all 4 offices
simultaneously, given that they're in London, NY, Chicago, and LA. Is
it possible to:
-Run domainprep, then install the first Exch 2003 server in NY and not
move mailboxes onto it, and keep the existing Exch 5.5 infrastructure
intact.
-Then fly to LA and run domainprep there, install an Exch 2003 server,
create a connection agreement, between NY - LA, not move mailboxes,
keep the existing Exch 5.5 infrastructure intact.
-Repeat for Chicago and London.
Again, I know you said that accretion may not be possible, but there's
no budget for bringing in outside help, so I have to do the best that
I can with as much safety as possible.
Thanks,
Joon

Certainly. That's what I did, a couple of times. It's been a while , so
I
don't remember too much detail, but MS has TONS of documentation on how
to
do that. 2 things you'll have to pay particular attention to are schema
updates and Connection Agreements.
That's for the straight upgrade stuff. But you have some serious
complications with your 5.5 topology. You can't get away with that kind
of
accretion in the >2K world as you could in 5.5. The way that Servers and
Clients do business is quite different -- sites are redefined, there's
close
integration with AD and DNS, there's Back End and Front End servers,
Cached
Mode, etc. etc.
If I were in your shoes, from what little I know of them, I would either
consolidate all the servers into one 2k3 servers, or, if I had to keep a
herd of them, I would bring in a consultant who knows how to plan a >2k
Exchange network.
And I would definetely take them off the edge, if that means what I think
it
means.
