I have a situation where we have migrated a ton of Solidworks files into epdm, then I created data cards that push custom properties to the drawings, parts and assemblies.

The issue is the migrated files already have a lot of custom properties in them that we do not use any more. I would like to purge these through a transition perhaps or maybe even dispatch impossible. Then the user can fill out the data cars and the parts, drawings or assemblies will have only the new custom properties.

Is there any way to do this?
