If that's the case (test conversion) then bring over everything you can as
fast as you can, then on conversion day you only need the small number of
new files.

We'll have a chance to test this with the POWER9 hardware before the actual
migration. That should shake out any ownership issues.

How could I do a restore/save, I don't know of common format?

I would expect to have object ownership issues when you move 20 million
files owned by the same profile. Unless that's been fixed recently for the
IFS.

Probably need to do a test perhaps. Perhaps multiple threads copying as well
if you can break it down to a list of files. (perhaps list to a DB first.)

Also how do you know files don't get corrupted during copy. May need some
sort of data comparison if those files are important to stay intact.

Save/restore to/from tape perhaps and then file comparison by hashing or
reading bytes.

Or initial move to NAS/SAN as Rob mentioned.

Rsync also comes to mind.

Or.....leave them alone and back up your Windows server. IFS is not
efficient with lots of small files.
