[ovirt-users] Ovirt 3.6 to 4.2 upgrade

Hi Is it possible/supported to upgrade from Ovirt 3.6 straight to Ovirt 4.2 ? Does live migration still function between the older vdsm nodes and vdsm nodes with software built against Ovirt 4.2 ? We changed a couple of the vdsm python files to enable iscsi multipath on direct luns. (It's a fairly simple change to a couple of the python files). We've been running it this way since 2012 (Ovirt 3.2). Many Thanks *Gary Lloyd* ________________________________________________ I.T.
