Hi All

Does anyone have any link or info or thoughts on the best way we can migrate from our current BES 4 with Exchange 2003 to BES 5 and Exchange 2010?

I am currently planning our exchange server migration and we will be running Exchange 2003 and 2010 in co-existance whilst i get everything moved over. Im aware that i need BES 5 to support Exch 2010 but trying to figure out a good migration plan for BES during this transition period...

so anyone done it? Whats the best way?

Thanks
Stewart

Move everyone to BES 5 first. Then do the mailbox moves. I would suggest using the enterprise transporter to move to BES 5 if you can.
