We recent acquired a new company. We will be moving them from their Exchange 2003 on-prem environment to our Exchange 2010 (private cloud).
I don't want to get all complicated with establishing domain trusts in order to migrate mailboxes. Our fall-back solution is to export to PST, and reimport. In doing some research, I've discovered "MigrationWiz.com". This service allows you to connect to the old server and migrate everything to the new server. It works well and is relatively inexpensive.
I've tested it with 10 users and found that connectivity can be a problem. I guess it exposes the weaknesses with your Exchange servers.
Anyway, we've decided to roll out 2010 servers on-prem for this new company. I'm trying to find a piece of software that will perform a similar staged mailbox migration, but since both the old and new servers are on-prem, I'd like to run it in house.
Anyone know of such a piece of software?
