I realize you may be doing a mass migration and am only pointing this out as a base for ideas...
I created a REXX routine that could be invoked from a TSO DSLIST where the user could simply type TT beside the dataset name and the routine would calculate the next generation for that dataset and invoke the TLMS utility to perform the tape to tape copy. That way I stayed with the native tools and could copy any tape, I believe even foreign tapes since TLMS was doing the copying. This was helpful in doing single tapes when we were moving from 3490 to 3590 cartridges but would definitely need some tweaking to do something on a more mass level.
