More precisely: You can't change the management class _name_.

What you can do (if you have to), is modifying the management class
and copy group having the _name_ that is attached to the files in question
(and displayed by "dsmc query backup").

Best done when the relevant node is in a domain of its own -
which can be had via COPY DOMAIN, UPDATE NODE DOMAIN=,
and re-creating schedules & administrative rights as required.

Sure, by this approach you affect all (inactive, at least)
of the node's files having the same management class -
but often that's much better than having files expire too early.

And be warned that it ain't a pretty sight, and may be utterly confusing
to someone else, when - after such a change - you have a management class
named "2WEEKS" keeping its files for 10 years ... but sure it's possible.

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
