Multiple server versions?

Would it present a problem to have different server versions that clients connect to? I only ask because my preferred method is to update one server for a bit, see if any issues arise, and then later on update the other server/servers. Thanks.

As far as I am aware – and the developers could confirm or deny this – as long as the client versions are not higher than the server version, you’re typically good on that front.

This is recalling how you could run a 1.X client on a 2.X server, but not the other way around.
