Upgrade the master first, then the satellites. Ensure they’re running the same major version (major in terms of running lifecycles means 2.x). Clients should continue to work, as they need a relatively small set of cluster messages to operate properly. There’s no guarantee though that 2.9 satellites will operate with 2.6 clients. And then again, you’ll have to check the changelog. Sometimes things are specifically fixed for the client, for example respecting ‘concurrent_checks’ on the client with command_endpoint enabled - that requires an updated client then too to properly work of course. If there’s a breaking change with older clients, you’ll see that in the upgrading docs. Be advised on the other hand, that we don’t regularly test older client versions and prior to upgrading you should test these version combinations of yours.
