We have a windows client domain that writes to its own tape pool for about 200+ 
Windows clients (Collocation On Primary Tape Pool / Off on Copy Pool).  We 
would like to split the clients out in to additional domains for restore 
purposes.  

The question I have is how do move the data of client A in Domain A to a new 
Domain with a new tape pool.  

Options
Move Data moves backup data at volume level not client specific.
Export / Import Node is only for server to server...
Upd node to new domain and hope TSM will Magically migrate data?
Upd node to new domain and hope TSM will know to restore previous data from old 
tape pool etc?
Make New Domain's backup Copy Pool Absolute to force a full? Then let old data 
drop off?

Appreciate any input.

Regards,

Charles
