If you have a lot of scratch tapes, the easiest is this:
- Set the tape pool to read only
- Replace scratch tapes with new tapes
- Create a new tape pool and set this as nextstg for the old tape pool
- Migrate data
If it is just a few scratch tapes, you can move volumes one by one in the same pool:
- Set the old volumes with data to read only
- Use the move data <volname> command which will allocate a new available scratch tape
