shared between Orgiganization)
- According that the migration has to be executed in several steps, which means,
that not all Users will be migrated in the same steps.
Q1- We need to understand which is the right Tool to migrate that mailbox
from Exchange 2003 to Exchange 2007.
I know that EMS (Exchange Managemnt Shell) cmdlet Move-Mailbox
has this capability. Is it true ?
If so, we need to set-up some connector between the two Exchange Server.
The Mbox Migrations Wizard embedded in the ADMT V3.1 is only
for Exchange 5.5 Source mail server, iti is not the right one.
Q2- We need to configure both Mail Server (Source and Target) to share the
same SMTP Domain: @mail.com
Because some Users will still have Mailbox on the Source Mailbox Server (Exchange 2003)
and some other will have not longer Mailbox on Exchange 2003, but only in the new
Exchange 2007 Organization with the Mailbox Server.
The only way that we found is in the Microsoft KB 321721
(How to Share and SMT address space in Exchange...),
changing the Authoritative SMTP Adress form the SOurce to the Target.
But we don't know whther o rnot after this modification on the source Exchange 2003
Server the User that still on Exchange 2003 continue to work properly.
The same doubt for Sending/Receinving Email between two User in the @mail.com, but
with the Mbox in different Mail Server (e.g. Exchange 2003 and Exchange 2007).
Thanks for providing same suggestions.
