I would say NO, that would cause you problems. When you restart the server
it will expect the files to still be in the disc pool if you skip item #2.
In this case you would have to do a restore stgpool to make the server
happy. You will not be saving any time by skipping item #2 and most likely,
it will take you longer.

Do it this way. If you migrate and backup the disc pool to the same tape
pool, skip item #1 you've described below. If you backup the disc pool to a
different pool than you migrate to, do both items 1 and 2 below.

        Take care,
            Al

Subject: Migration Question


Hi Guys,

I have a quick question for you

I am about to delete all of the promary disk storage pools for a
resizing and re-placement exercise.

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)?.

Kind Regards,
