As the title says, I need to perform what is a very simple operation when completed manually in the ArcCatalog tree --- move data from a 10.1 FGDB to a 10.0 FGDB. This is now done by simply selecting everthing in the 10.0 FGDB and deleting, then selecting and pasting everything from the 10.1 FGDB into the 10.0 FGDB.
The catch: there are "Attachments" in 10.1 FGDB that need to come across too. Again, not an issue by doing this manually I say above. I have attempted to peform this with FeatureClassToGeodatabase_conversion and TableToGeodatabase_conversion, which works fine to bring almost everything over! However, it does not pickup the attachments or the attachments relationship class.
