Hello!
I’ve read the upgrade procedure documentation here Temporal Cluster deployment guide | Temporal Documentation.
Is there any advice regarding downgrades? I was met with the following error when testing a schema downgrade locally:
ERROR Unable to update SQL schema. {“error”: “error listing schema dir:start version ‘1.9’ must be less than end version ‘1.8’”, “logging-call-at”: “handler.go:78”}
Is downgrading the schema version something I should even consider, or is rolling back to the previous server version the way to downgrade?
Context: if an upgrade fails, my assumption is that I can get back to green by reseting schema and server versions back to how they were pre-upgrade.
Thank you.
