I think the easiest way to test forward migration is to have 2 ARCHICADs open at the same time: one with the old libraries and one with the new ones. Then I can simply place objects from the old library, and then copy-paste them to the other ARCHICAD with the newer libparts. If they are replaced during the paste, then forward migration is ok.
It’s quite fast, there are no problems with library reloading, and you can check visually the 2 different versions.
