TSM 6.3 Retention Trigger

Hello,

We are using TSM 6.3.4 on Windows server. I have two question.

+ I changed retention policy for example i changed Versions Data Exists parameter 3 to 2 etc. But there isn't any capacitance change. I guess my old data stamp to old retention policy. How can i trigger manually ?

+ I want to delete inactive backup data for some nodes is it possible inTSM 6.3?

Regards
