Hello,
We have two domains
Old Domain A with Exchange 2003 and BES 4.1.7
New Domain B with Exchange 2010 and BES 5.0.3

We have trust between domains.
Is it possible to migrate users crossover domains to save their app and files on BB devices?
Can I use BlackBerry Enterprise Transporter for this or I should wipe BB device and activate it on the new BES server?

Thank you

Corss forest between the domain works as long as the exchange org reamins same. if the Exchange org changes then we need wipe the device.
