Here's what I am going to do. I have a license for 128 slots, I am in
the process of buying the upgrade to 256. I am planning to keep both
libraries on line and connected to the one server. Oupps I am going to
need a second FC card. Can I have the two licenses installed at the same
time. If I remember when I upgraded from 64 to 128 the 64 went away. I
just need to keep the old library online for 60 days. That all we keep.

No the tape drives are not compatible. I am going from sdlt320 to LTO3.
As soon as the retention policy has expired on the data I can just
disconnect the old library.

Why would you need to wait until all volumes are listed as recycleable,
before deleting the old jukebox? Couldn't you (theoretically) just
physically move the volumes to the new jukebox? As long as you inventory
the slots, so NW knows where the volumes are, shouldn't that be all that
NW cares about (from a volume point of view)? He's asking about
restoring from the old tapes; presuming that the new jukebox/drives are
compatable, he should be able to read and restore the old tapes from the
new drives.
