There is a utility that was designed to raise the version of large quantity of Cimatron catalog parts.  It will also work on regular parts and assemblies because it is really just a macro to quickly open and re-save.

You must add a special flag (-Updatecatalog) to the Cimatron startup.  Go to the properties of the Cimatron desktop shortcut and add it at the far right end of the target line.

This will add 2 new functions to the Catalog MenuUpdate Catalog and Update Catalog Geometry.  The functions are about the same, but Update Catalog cannot do assembly files.
