You cannot dynamically convert a JFS filesystem to a JFS2 filesystem. Therefore the easiest way to perform the change is to backup the system using "mysysb" and "savevg uservg". I strongly advise testing this on a development system before trying it on a live system.

This procedure is not documented on official websites. Before running each of these, you should run the "mkszfile" and "mkvgdata uservg" commands and edit the files "/image.data" and "/tmp/vgdata/uservg/*" to reflect the change from JFS to JFS2. There is some more detail at http://comp.mailarchive.ca/unix.aix/2003-12/0600.html.
