Migrating old 2003 server with Exchange to new 2003 64-bit server with Exchange 2008

Migrating old 2003 server with Exchange to new 2003 64-bit server with Exchange 2008

Hi,

We were running Windows Server 2008 64-bit with Exchange 2008. The
hardware was unstable and eventually disaster struck and we lost the
entire machine. we quickly commandeered a standby machine, installed
Windows Server 2003 (32-bit) and Exchange 2003 on it, recreated the
mailboxes, had all the desktop/laptops in the company rejoin the domain.
It was not pretty. Mail was lost, profiles corrupted - generally *** .

This was 3 weeks ago.

Now we have a replacement machine. The guys supplying the machine is now
scared of Windows Server 2008, so decided to downgrade to the more
stable (longer in the field) 2003 server - but because our backups of
mail was in 64 bit Exchange 2008, it could not be restored without
considerable effort on their part. Therefore they decided to go to
Exchange 2008, 64-bit.

They want to do the same as last time - recreate the mailboxes, have all
the desktop/laptops in the company rejoin the domain. Understandably we
are not very enamored with this idea. A bit of research revealed that we
do not have to go this route.

From my research it seems we should:
1. Introduce the new server, without Exchange (or Exchange disabled) as
a member server.
2. Make it a DC.
3. Wait till the AD has propagated.
4. Demote PDC.
5. Promote new server.
Now the new server should be acting as the new PDC and users should be
authenticating from it.

The part where I get stuck is how do I migrate the existing Exchange
2003 mailboxes to Exchange 2008, and still recover the mailboxes.

Any suggestions welcome.

1. Migrate from Exchange 2000 old old server to Exchange 2003 on new server.

2. Migrate from Exchange 2000 old old server to Exchange 2003 on new server.

That doesn't mention anything about Exchange 2003. Are their no differences?
