Assign to a new TSM server the management of files previously managed from an old one

Hi all,

I'll try to explain better my problem starting from my environment:

- we have 2 HPC cluster, for example C1 and C2;
- on C1 is mounted a GPFS file system ( for example FS1 ) managed by HSM;
- on C2 is mounted a GPFS file system ( for example FS2 ) managed by HSM;
- FS1 and FS2 data have been managed, until today, by the same TSM server (v.5.5).

Now, I would like to do this:
- create a new TSM server and some new TSM clients ( using a more recent and supported version );
- continue to manage FS1 data (resident and already migrated data) using old TSM server;
- start managing FS2 data (resident and already migrated data on old TSM server) using new TSM client and server.

PROBLEM: FS2 file system is about 171TB and 400TB (of FS2 data) have already been migrated using old TSM client and server.

How can I "move" FS2 HSM managed data from old TSM server to the new one?
I would like to avoid recalling all 400TB ( little by little ) and migrate them again using the new server.
Someone could help me?!

Thanks again.
