Upgraded our staging clusters to v1.19 this quarter.
Lessons learned: - Always check deprecations beforehand (kubectl deprecations) - Test ingress controller compatibility early - Pod disruption budgets saved us from some flakiness
Tooling we used: - kustomize for manifests - velero for backups
Planning is everything. Production upgrade next quarter!
