OK I'm confused. :)
I asked: "That sounds great! So to confirm, there are no technical gotchas
that are going to prevent data movement from one media type (LTO1/2) ton
another (LTO3/4)? Anyone else done this?"
I receive the two following responses:
"Well, yes there is.
An LTO4 tape drive will NOT be able to read any data from an LTO1 tape
cartridge.
The LTO specifications call for any LTO cartridge to be readable and
writeable for a drive one level up (LTO1 to LTO2, for instance), and for any
LTO cartridge to be readable ONLY for a drive two levels up (LTO1 to LTO3,
for instance."
And..
"That's correct, one of the real nice things about TSM.
This is basically the same as migrating from any kind of
disk pool to any kind of tape pool, doesn't matter the
media type/technology.
You do need to remember though that after you have
migrated ALL of your onsite tape pool and it's offsite copies
have been made, then you need to "delete volume" with
discarddata option on the OLD offsite pool tapes, or else
old tapes will still be there."
Help a brother out...can both responses be correct? So far I have 2 to 1 in
favor of TSM can handle it. But it's not a poll, either I can or I can't do
it, right? :)

Just define up your new tape drives/devc/stgpools and then set the NEXTPOOL=
on your LTO1/LTO2 stgpool(s) to the new LTO3 or LTO4
stgpools. Now just MIGRATE STGPOOL the LTO1/2 over to the LTO4 pool. No need
to do individual MOVE DATA/NODEDATA. Just let migration
handle it all for you. Cancel it and restart it as you need.

Subject: LTO1/LTO2 to LTO4 migration?
Is it possible to run 'move data' or 'move nodedata' commands from either
LTO1 or LTO2 device class to LTO4? What about from LTO1/2 to LTO3? Has anyone
done this?
God bless you!!!
