we are running version v17.2 and have modified a customers design which was in v16.6. as 17.2 is not backward compatible is it straight forward to export a placement & routing file from the 17.2 pcb to be imported into the 16.6 version?
Delete all the routing etc and use the 2 files and regenerate the pcb data in the 16.6 version
i know exactly how to do this in other pcb tools but i'm new to allegro!
regards
carl
