Hello,
when alfresco was migrated to a newer version (5.2->7.x), incompatible extensions were removed (not installed), and also their custom model is missing (aspects and its properties). Files and folders In Alfresco have this metadata marked with a special flag and the document cannot be edited in Share (Edit Properties). I created missing custom model again by model modeler and it seems it worked well.
In this moment, I would like to remove old unnecessary aspect from all documents in the system, how to do that?
Thank you!
