Does anyone have hints on how to move a user/handheld from one BES 4.x to another which do not share the same SQL configuration database?

I administer several BES on Lotus Domino. I need to move a few users from one BES to another which run within the same Lotus Domino domain but do not share the SQL database because of slow WAN links between them.

Currently, all I know is I can wipe the handheld and do a new enterprise activation on the new BES in order to move it. But this way the users looses all his preferences (i.e. settings, font sizes and so on) which are backed up by BES.

Any idea on how to export the handheld backup from one BES and import it into another? Where is the handheld configuration backup stored? In the SQL configuration database? In the bbprofiles.nsf Domino database?

Manually backup the device. Remove the user from their current BES. Wipe their device. Before you turn the radio back on, restore their data and correct the time zone. Add them back to the new BES and reactivate.

Just my opinion.
