Dear all,
I am migrating our mail server from Exchange 2007 to 2013. Untill now not many problems encountered, I have set up a 2 members DAG for redundancy and most of Exchange functions and services are working like a charm (except sharing schedule's when you work with Outlook 2007 on the Exchange 2013 server).
Now comes the challenge: Our company has bought another company. They have their own domain. We need to migrate all their mailboxes to our mailserver, with as little downtime as possible. Their mail addresses needs to be kept the same, but they will work in our mail server.
I wonder if someone has experience on doing this? How can I connect the mailboxes to our domain, keeping the old known address to clients. This company delivers very critical services to diverse clients, and every 5 minutes downtime is actually too much, and changing addresses is not possible. Can someone help me with this?
All help will be appreciated!
Regards,
Cornelius
