Good day all,
We are in the process of mapping out a plan to consolidate multiple TSM
servers into a single instance and a single library.
 
Currently I have 3 separate TSM instances using LTO2, LTO3 and SDLT320
libraries. Housing approximately 300 Tb of data.
I've been through a library conversion once before and that was a
nightmare and took over a month to complete and didn't include the added
complexity of merging TSM instances.
 
The plan. 
Step 1: Replace the library using LTO2 with a larger expandable library
using LTO4. Migrate all data from LTO2 to LTO4. 
Step 2: Move the data from the other two TSM instances to the TSM
instance using the LTO4 library.
Step 3: Celebrate.
 
My question:
Does anyone know of a painless way to move the 90+ TB of data from the
TSM instance utilizing the SDLT320 library to the TSM instance utilizing
the LTO4 library ?
 
Thanks,
Duane
