we are in the process of migrating from DLT to LTO, with no options for
mixed media, because of space requirements 2 DLT libraries were connected
to old servers for recoveries, one system will be coneected to both the old
and new libraries with the DLT drives marked as readonly (less drives than
tapes) the 4th system was a legato server with attached jukebox and we are
adding the new jukebox to a new storage node - this is nicer than the other
migrations which are "big bangs" and if things go wrong need to be
regressed to the original setup before the main backup window is reached,
this storage node can simply have clients migrated to it as and when.
