Hi,
I have plan to do migration from Lotus Domino to Exchange Server 2013, because we can do big bang migration, we need to do migration with coexistence schema. But now i have question about the SMTP routing from external. By now, the existing mail system had mail gateway connection to Lotus Domino server. When I have my Exchange Server ready, what should I do to the SMTP routing? Can I set mail gateway to send email to both Lotus Domino and Exchange Server? Or just let the existing routing where mail gateway only send email from external to Lotus server and then it works with the Internal Relay that has been set?
Thanks before for all your respons
Regards,
