Verifies that the user account is associated with a valid email address.
Verifies that the user account exists in the source domain.
Verifies that the user account does not already exist in the destination domain.
Verifies whether it can preserve the user ID that is associated with the user's BlackBerry device.
Verifies that an IT policy can be applied to the user's device.
