Exchange migration - move from 03 to 2010 first?

I have Exchange 2003 in one domain (Domain A)

I have Exchange 2010 in another domain (Domain B)

I have a third domain where we will start with EXCH2010 and eventually move to 2013. (Domain C)


Do I:

1. Move A to C, and then B to C?

2. Move A to B, then B to C?

Does Exchange handle more than one domain?

Is it in the same forest?
Exchange can handle multiple SMTP domain and domain in same forest.

Both Exchanges exist in different AD's and different domains.

All three domains are trusted.

Then this would be a cross forest migration. Also there is no path migrating from Exchange 2003 to Exchange 2013. you have to migrate first from exchange 2003 to exchange 2007/2010 then migrate from exchange 2007/2010 to exchange 2013.

Here is the link.

I think, Exchange server as such you cant move to other domain(outside forest), but users can be migrated

Microsoft has developed tool for this

I understand what you guys are saying, but that doesn't really answer my question...

I currently have two domains in production and a new third not being used.

Do I:

1. Move A (2003-production) to C (2010-production), and then later move B (2010-production) to C (2010-new)?

OR

2. Move A (2003-production) to B (2010-production), then B (2010-production) to C (2010-new)?

How many users involved?
If a lot, I would migrate the 2003 server to 2010 (same domain), then cross forest straight to the new domain.
That will save doing PST file type migration.
Then move b to c, again on cross forest. Once you have everything moved, then go Exchange 2013 (SP1 should be out by then).

Simon,
this says that I can't go from exchange 2003 to 2010 in server 2003.

You cannot in-place, but I didn't say in-place upgrade. I said migrate. So that will require a temporary server.

First approach is fine and no need to migrate from A to B.
But after migrating to C from exchange 2003, you need to decommission exchange 2003.

After decommission of exchange 2003, you can go ahead with exchange 2013 in domain "C"

He he. Nice.

Good call. So you're saying to temporarily build a server just to house exchange 2010 on domain A, do the migration, then move 2010 to the new domain (C).
Is that right?

Good said Simon.
Direct migration from A (2003-production) to C (2010-production) is not possible. You will have to move either to an Exchange 2007 or Exchange 2010. You can check this link to get appropriate direction : Mailbox migration to exchange online
However, you can have try any good software like http://www.exchangemigrationtool.com/ by which you can proceed further moving exchange server direct from exchange 2003 to 2013 without any boundation.

Once you have everyone on Exchange 2010, even on a temporary server, doing a cross forest migration becomes pretty easy, just make sure that you read up on the process on TechNet first. No need for a third party tool.

Best solution I've found! Totally took the complexity out of the migration.
