Emqx upgrade from 5.0.2 to 5.7.2

[akshayparseja]

Hi ,
We are currently upgading emqx which is deployed via operator on k8s . During this upgrade we need to upgrade the operator.
Here on changing operator chart it immediately starts creating pods using current EMQX Custom resource of kind "emqx" which actually has api version of /alpha , depriciated in the new operator.

Is there a way to upgrade operator and emqx without downtime since there are CRDs which are common and having a new operator is affecting current infra which is not something we want.

Hi, @akshayparseja Sorry for delay. I'm in Chinese New Year Holidays. EMQX has so many change between 5.0 and 5.7, so I think might have some issue if you direct update EMQX version.
And could you please tell me the version of the EMQX operator ?
