Mixed 2.3 and 3.1 cluster

Hello!

Sorry, this is a basic question. But, I prefer to be sure.

Can I add a 3.1 node to an existing PVE 2.3-13 cluster?

Thanks in advance,

Join is possible, but, does not work.
For example, live migration on 3.1, requires mandatory version 3.1. In mixed status 3.0 - 3.1 live migration fails.
And this is just an example

Thanks for this clear answer. Will stay away from mixing.
