If you need to release space now, it sounds like the procedure should be: 1) Update the library 2) LLA update on all sharing LPARs in the sysplex 3) Update at least one additional member on any system in the sysplex You may need to do this multiple times if the library couldn't hold all the updates in step 1 (no secondary, vol out of space, etc.). This is less risky than COMPRESS of a LLA controlled PDS DSN with DISP=SHR, but still a PITA. If you already had a procedure to remove the PDS from LLA control prior to COMPRESSing it (and re-adding it to LLA when done), I guess that same procedure could be modified and used instead of the LLA update. So back to the OP's question... I can't see any real operational benefit to converting an LLA controlled PDS to PDSE. Now if the PDS is not LLA controlled, thats another story.
