| | Exchange 2003 to 2010 transition and BB Users
Please Login to Remove!
I hope someone can help me with this before the inevitable "My Blackberry isn't receiving e-mail ticket"
Currently we have Exchange 2003 and 2010 running.
BES 4.1 is running on the 2003 box.
BES Express 5 is running on a separate VM working in conjunction with the 2010 box.
All systems are working fine at this time.
I'm in the process of migrating mailboxes from 2003 to 2010. Non-BB users are a no-brainer. However what about BB users on 2003? Should I migrate mailbox first then move them to BESX? Or vice versa?
I would prefer a seamless transition where service to the end user is unaffected but completely understand if this is not possible.
