If you change the management class (for example by adding an INCLUDE statement 
to bind a file to a different management class), the next time you run a backup 
you will see "files rebound nnnnn" in the statistics.  TSM will just change the 
management class for the files it finds (files that still exist on the hard 
drive).  It will not resend the data.  

There is not a way to change the management class for inactive files that no 
longer exist on the hard drive.

Subject: [ADSM-L] Changing management class wihtout retransferring all data

Hi,

is there a possibility to change the management class without transfering the 
data again to TSM server?
We have to change the management class of approx. 50TB of data (12 millions 
files) and we don't want to backup all the
data again.


Thanks.
Alex
