I think the answer to your question is technically "no".

The recommended way to move the metatdata is to set up DB2 HADR to replicate 
the DB, which accomplishes what you want.
(If your DB isn't too big for your bandwidth, you can also backup the DB to 
disk and ship the DB backup via FTP, but that's another story.)

There is an STE presentation that includes the DB2 HADR setup:

Subject: [ADSM-L] TSM 6.3 node replication

Hi,

I'm keen to make use of the new features in TSM 6.3, one of which is node 
replication.  However, the client I'm working with has limited bandwidth 
between datacenters and there is no way that 4TB of change a day is going to be 
copied across the link even if it is deduplicated.  Is there a way to replicate 
just the metadata and not the actual data, whilst shipping copy pool tapes by 
courier?  My original, pre-release, understanding was that this was possible 
but the documentation is leaving me less clear.

I was thinking along the lines of configuring nodes for replication, but 
disabling replication for the filespaces - but does that copy the entries for 
data contained on the copy pool volumes even if it doesn't copy the objects?
