Upgrade
Upgrading to a new version of Crunchy Postgres for Kuberentes (CPK) depends on the tool used to install CPK and on the version being upgraded to. This section provides detailed instructions for upgrading CPK 5.x using Kustomize or Helm, along with information for upgrading from CPK v4 to CPK v5.
Info
Depending on version updates, upgrading CPK may automatically rollout changes to managed Postgres clusters. This could result in downtime--we cannot guarantee no interruption of service, though CPK attempts graceful incremental rollouts of affected pods, with the goal of zero downtime.
