Are both Exchange servers in the same Exchange Org? As long as the mailboxes are all in the same Org and you grant appropriate permissions on each Exchange server per the install guides you can move users between wherever / whenever.
The key with this will be to upgrade the current one to 4.1 and then connect the new server into that 4.1 database (running the same version of 4.1). then you can easily move users from one BES to the other.
