I'd change it to:
backup stg disk copy
backup stg tape copy (for anything that might have been migrated during the
night. Do it this way since the copy pool tapes are already mounted and
ready to go)
migrate disk tape

Thank you, and all the others who have responded. I inherited *SM and those
who set it up before me were under the impression that it WOULD back the
data up twice. I believed otherwise but I gave them the benefit of the doubt
and asked. Again, thank you very much for responding to my question. Looks
like I've be able to shave 2 hours off of my morning processing. (That tape
to tape copy AFTER migration was a killer. Especially with 3490 tapes!)

+
+
+ Hello fellow *SMers! I'm thinking of redoing how our backup pool
+ migration/tape copies process is done to increase efficiency. We are
+ currently processing this way:
+
+ Backuppool (disk) migration to primary onsite tape pool (3490).
+ Tapepool (onsite) copy backed up to vault (offsite) tape copy pool.
+
+ What I would like to do is this:
+
+ Backup disk pool to vault tape (offsite) copy.
+ Migrate disk to tape (primary onsite) copy.
+ Backup primary tape pool to offsite pool to catch any migration etc. that
+ may have occurred during the last 24 hours.
+
+ My concern is this. I do not want to back up the data TWICE from the disk
+ pool to the offsite pool. (Once from disk to offsite pool and again from
+ onsite tape pool to offsite tape pool.) That is, is *SM smart
+ enough to know
+ that the data that was backed up to the vault (offsite) pool prior to
+ migration has already been backed up and will not back it up
+ again from the
+ onsite tape pool to the offsite pool when the "BACKUP STG
+ TAPEPOOL COPYPOOL"
+ command is executed?
+
+ My environment is TSM 4.1.0.0 on OS390 with 24 3490 tape drives.
+
+ Thanks for listening!
