unfortunately no, there are far too many dependencies in the whole DB to try to merge them without causing the server to die. if they're in the same version the safest bet is to use bat to export/import the information for phones. all other stuff will need manual work.
remember things like MRGL and plenty of other stuff needs to be created before importing.
