Is there a reason you are wedded to the old config? With the same config,
index, tapelist, ... as you use the new lto tapes you lose the index and
other info regarding the dlt tapes even though they are still good if you
need to locate data on them.
You could start an entirely new config eg. DailySet2 or DS1 or DS-lto.
You could set up your labelstr template to uniquely note the lto tapes.
You could number the lto tapes in a different range, say 101-124.
Any of the above would preserve your ability to continue to use the dlt
tapes, though without a config you would have to reset the tape devices.
