I don't have a real answer except perhaps to create a new LVM for XFS then slowly migrate files from one LVM/fs to the other. As you fill space on one, shrink the other filesystem to reclaim those LPs back into the VG. It's messy but should work. AFAIK, there is no in-place conversion utility as the two filesystems are quite different.
XFS doesn't support shrinking. :)
(patches existed for it but they were never accepted)
