BPM delta migration from 8.2 to 9.12


We have migrated all the BPMs from 8.2 to 9.12 . During testing we have found one of the BPM is out of sync with production . We need to do a delta migration of that BPM from 8.2 to 9.12.

Instead of full migration from 8.2 to 9.8 and then taking the delta from 9.8 . May I know whether any better migration option is available.
