Hello. Is there any consideration or caution for upgrade starrocks cluster to 4.0? I'm currently using 3.5.6 and want to upgrade my cluster to 4.0, Is it enough to roll-out new version? I couldn't find any upgrade note or guides in documentation.

Yep, I feel this is also missing for me, clear upgrade plan, changed defaults and more IMO kafka style upgrade plan is the best reference

I'm curious as well. In our case this we're running starrocks shared data in AKS deployed via helm, so it may be as simple as updating the versions in our helm chart values file.

Seconding this concern, 3.5.7 just released now too, a couple days after 4.0. Do we upgrade to that first, or should we go from 3.5.6 to 4.0?

@Allen Li do we have any prospective guides or tips to migration here?

You can upgrade from 3.5.7 first. 4.0 is just released, it needs some time to be stable.

@Allen Li thank you, is it necessary to upgrade to 3.5.7 before going to 4.0 when we decide to upgrade? Is there anything we need to do to upgrade other than change the version of the FE and CN images in the helm charts and let helm handle the upgrade?

If you want to upgrade to 4.0, you can skip 3.5.7.

@Allen Li can I go back to 3.5 once upgraded in case of problems?

Yes, 4.0 can rollback to 3.5

Thank you for replying
