I'm going to upgrade my 6.8.2 cluster to 7.4.1 and also rest high level client.
There might be a time window when client version and cluster version are different:
- client 6.8.2 with cluster 7.4.1, if I upgrade cluster first.
- client 7.4.1 with cluster 6.8.2, if I upgrade client first.
Which one is supported regarding compatibility?
