Anyone with experience of running Flyte using the multi-cluster approach? We were wondering how we would be able to handle upgrade in that case to avoid downtime

Thanks @Ketan (kumare3), I guess you mean adding new cluster with same version of the services right?
My question is more when there is a new version of Flyte that we want to migrate to. I believe that the admin service is communicating with the propellers but is there backward compatibility? see the diagram
Or maybe there is an other approach?

No this is backwards compatible- @Jonathan Lamiel

We try to never break this contract
Flyte is deployed in multi cluster environments consistently

Also we cannot ever guarantee atomic switches
Running workflows will remain
