Sorry if this has been discussed before.
What if there was an option in the "Export As A Catalog" function to have the export done in the previous version format? For example, "Export As A Catalog" folders or files that have been processed in LrC V 13.x in a format that can be Imported into LrC 12.x.
This would ease the problems of users who have already processed images in V13.x and because of bugs or whatever need to go back to V12.x.
