Mark,

The simple answer is duplicate.  And that license is part of the base 
product.

To make the duplications "faster", you'll want to make sure both 
libraries (actually drives for duplication) are connected to the same 
host (to avoid sending data over the network).

Once they've migrated all the data, they can expire the originals (AIT) 
and all future restores will request the copy of data that's on LTO.

As far as how to do it... You'll probably just want to get a list of 
all the backup ids and break them up by retention level, then feed each 
list of backup ids to a bpduplicate.
