I have a question regarding the effect of changing the retention period 
(retver=nnn) of an Archive Copy Group.

Are all objects previously stored via this archive copy group given the new 
retention or only those stored after the change is made?  

If the answer is the latter, is there a way, via a command or the API to set 
the expiration of a previously archived object?

Thanking all in advance.
