Have exchange 2003 with blackberry server, need to move to exchange 2010
I need to determine how to proceed with the move without killing the blackberry server.
I have installed exchange2010 and want to set up active sync in it.
Will it work on the 2010 exchange server if I do not move the mailboxes?
If I move the mail boxes to the 2010 exchange, will the blackberry server still work?
I plan to route port 443 to 2010 server an skeet port 25 at the old exchange, or is there a better way
What else do I need to watch out for.
