Good day,
In AutoCAD Electrical there is a pretty robust migration utility for the databases. This allows you to make choices on source / destination database as well as merge, overwrite etc... You can access this command in AutoCAD Electrical under the Projects pull down menu, then Extras, then Migration Utility. If you are using AutoCAD Electrical 2010 and are utilizing the Ribbon interface it is on the Project Tab, Other Tools Panel then Migration Utility.
I hope this helps.
