Hi

Our four existing PVE hosts are running 7.0-11. The only 7.0 install media I have is for 7.0-8

Is the 7.0-11 ISO available anywhere? I can't seem to locate it.

Am I OK joining two new 7.0-8 hosts to the 7.0-11 cluster? If not, is there a way to upgrade from 7.0-8 to 7.0-11? It'd only be for a day or two until we upgrade the lot to 7.4.

There's not enough RAM available on the existing four hosts to migrate VMs off a host and upgrade it to 7.4, migrate them back, do the same for the next host, etc, then join the two new servers after building them with 7.4. Hence the two new hosts to get us up to N+1. We could go with PBS and restore them from backup, but I'd rather not do it with the extended downtime that'd entail.
 
We only release one ISO per minor version (e.g. one for 7.0, one for 7.1, etc.). Using the ISO that you have should be fine.
After the node has been added, I'd recommend to update all nodes to 7.4

Hope this helps.
