[ovirt-users] Re: Upgrade from 4.2 directly to 4.5

Hi Sandro I’m writing back to thank you for the support and give a feedback. I was unable to properly restore the engine from 4.3 to 4.5 (or even 4.4); there was some errors during the network phase and I think that was because ovirtmgmt was running on top a bond0 and in the 4.2 days, when the engine was originally deployed that was broken and unsupported. After 4 or 5 tries I ended up reconfiguring the entire engine in a brand new one. It was faster… there was a lot of errors on OVESETUP_OVN/ovirtProviderOvnSecret and I gave up.

Thank you.
