Hello Gary, as far as i know upgrade path isn't direct and you have to migrate first to 4.0, then 4.1 and finally 4.2. You can migrate vms from 3.6 to 4.0 IIRC. But don't know if mixing 4.2 and 3.6 it's possible. Luca On Fri, Feb 9, 2018 at 3:06 PM, Gary Lloyd <g.lloyd@keele.ac.uk> wrote:
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
