We are in the midst of trying to upgrade everyone in our organization from ArcGIS 10.0 to ArcGIS 10.2.2. We have several ArcPy scripts that copy and merge feature classes from our 10.0 SDE and output to a file geodatabases. As we recode some of the older scripts to work with our new ArcGIS 10.2.2 setup, I've found that the feature class outputs from the scripts running from 10.2.2 are not readable by ArcGIS 10.0. The geodatabase was created in 10.0. ArcCatalog 10.0 can open the geodatabase, view properties of the geodatabase and feature class, but it can't preview it; ArcCatalog straight-up crashes. Even stranger is that existing feature classes in the same geodatabase that weren't updated by the script will preview fine.
Unfortunately, we aren't quite ready to retire these scripts. Any ideas on how to make this all play nice together?
