Proxmox 3.4 two nodes with quorum disk upgrade

[GabrieleV]

Hello,
is there a migration path to 4.x for those installations made with two nodes and a quorum disk ?
How can we manage a cluster with only two nodes in 4.x as there is no qorum disk ?
I have some clusters like that, and customers cannot afford threee nodes ...

Thank you !

You can migrate, but you cannot activate HA on a two node cluster.
