Does anybody know how to do this?

We have a number of ADSM Servers (V3R1 PTF 2 on NT 4.0) and have a number of 
ADSM clients on NT backing up to each server.

We have registered the appropriate number of client licenses for each server.  
However, we want to move some of the clients and point them at a different 
server.  

How can we de-register client licenses on one ADSM server so we can register 
them on another?

Any help would be greatly appreciated.

Regards

Phil
