[ovirt-users] Q: Cluster compatibility Level and Old v4.2 Nodes

Hi, I have quite old nodes from early 4.x era (with CentOS 7.6, cluster compatibility 4.2 level), and oVirt Engine 4.4. 2 nodes have ovirt-release42. Upgrade to oVirt Engine 4.5 engine required cluster compatibility >= 4.3 level. Nodes have been installed with stock CentOS 7.6, not oVirt node image, their upgrade is quite problematic right now. Is it possible to upgrade to cluster compatibility 4.3 while having old 4.2 nodes? Thanks in advance. Andrei
