Hi!
Have you seen this demo?
http://projects.db4o.com/wm6contactsync
Here dRS is used to synchronize the device with an external db4o database using a client server connection.
With regards to moving your database check you may run into trouble if the assembly name, any class name or namespace are different between your Windows app and the device app. If this is the case please check Aliases in the reference doc:
