I have two FGDB's, both with the same feature classes. I have a hydrants feature class in FGDB 1 that has attachments (pictures) related and want to merge/copy those features to FGDB 2 in its hydrant feature class. Is this possible? I have tried copying the features first, but the global id's change and then the relationship with the attachments do not function properly. I have tried to export the feature class from FGDB 1 to an .xml and then load it into FGDB 2, it says it will overwrite the entire FGDB.
