Exchange 2003 from one forest, to Exchange 2010 in a different forest

Hi all,

Do you guys have any tips for the following?

Exchange 2003 with 100 mailboxes currently exist at datacenter 1.

Exchange 2010 with 0 mailboxes currently exists at datacenter 2.

We are going to be moving all mailboxes from EX2003 to EX2010, but not sure what the best approach may be.

I'm happy to export all mailboxes manually and add these in, as a last backup option. AlsoI'm , happy to use Exmerge to get the mail out, will it allow me to import the mail into Exchange 2010?

Do Exchange 2007/2010 Powershell commands work across forests? Am I able to 'pull' the email in any way from the Exchange 2010 servers, directly from 2003?

If I can't do this all in a weekend, I'm going to be setting up a phased approach of:

Move an account to the new server and give it an additional domain in the Exchange 2010 forest. (effectively having 2 SMTP domains)
Delete source account and set up a Contact in Exchange 2003 and add this account to all its old memberships of the account deleted. This contact will have the email address of a 'temporary' domain, that I can point to the new Exchange 2010 server. This will allow the deleted recipient to keep getting its emails from its current distribution groups.


Anyway, to get to the point.
Is there a supported/correct way of doing this move with the tools available with Exchange 2010. I can only seem to find tools/resources for doing this move from servers within the same forest.

Thanks

Great, I've set up ADMT and the password service. migrated the account.
I've also copied the Exchange account over without problems. Excellent!

Is there a way that these 2 exchange servers can co-exist?

I was planning to do this over a weekend, however it may need to be done over a month instead and I'm worried about people sending messages to distribution lists and they not getting to the correct mailboxes.

Can you give any further advice on how to approach this?

Thanks again!

Just FYI, i know how to set the domain as an internal relay on exchange 2010, i'm not familiar with exchange 2003 on how to set up the connector to route up to exchange 2010 for undeliverable addresses?
