I'm doing a cross-org Exchange migration.
Source forest/domain is AD2003 with EXCH2K7 (DOMOLD.LAN)
Target forest/domain is AD2008 with EXCH2K7 (DOMNEW.LAN)
both ADMT and cross-org mailbox migrations are working fine
My problem is in exchange routing messages : the public smtp domain is the same in the 2 forest : mydomain.net
How can i route messages from EXCH2K7.DOMOLD.LAN to EXCH2K7.DOMNEW.LAN for the same SMTP domain, during the migration phase when my users are located both in the source and the target domain for internal email communication purposes ?
Hope you'll understand what i say
Thanks for your responses
