@estebanetcheverry I’d love to see experiences like this shared in the new wiki space! See Sharing our Runbook with the community (Redwood -> Ulmo in a K8S deployment) - #2 by sarina

I wanted to let everyone know that we’ve started a wiki space for people to share tips & tricks for upgrading instances - we’d welcome more pages drawn from your own experiences.
