Roy, You don't have to do the backup of the diskpool first, but why wouldn't you? That is what you should do every day anyway. If all the data in diskpool has already been backed up to your copypool in your daily processing, it will only take a few seconds and you'll have piece of mind when you hit return on the del volume command.
Before migrating the data to tapepool, however, do an update stg diskpool cache=no That will purge all the cached files in the diskpool during migration so you shouldn't have to add the discarddata=yes when you delete the diskpool volumes.

IBM have given me their recommendations as:- 1. Backup stgpool. 2. Update lo mig and Hi mig to 0 to migrate everything to tape. Now, am I right in saying that option 2 is un-necessary, as this data should already reside on tape anyway (as it would have been backup up sometime when a "backup stgpool" was taken)?.
