You can use "File -> Import Profiles" to copy profiles between two "profile storage" files.
The idea is to open a profile storage and then copy the relevant profiles from that to the current one or the other way round.
Or, if you are using the properties based format, you can simply copy & paste the relevant lines between the .properties files
Drivers are indeed identified by name (and driver class), so if the names are the same this should work without additional steps.
