I don't know this side of EMC, but let's assume, that nothing will be changed on the underlying device during changing the connection type, then you need several additional steps:
-1. make backup
0. notice all PVIDs of all disks, you have
2.5. exportvg all volume groups, rmdev all the disks, you plan to change
4.5. make sure, that you see the same PVIDs on the new disks. If you don't - go back and doesn't try to do anything further.
5. importvg all the volume groups, you exported before.
It could be also good to notice VG major numbers. Sometimes they are useful.
