This blog post discusses a new technique for upgrading Red Hat Advanced Cluster Management hubs for Kubernetes that mitigates the risks associated with traditional in-place upgrades. It introduces a parallel hub deployment with cluster migration strategy, which allows for seamless migrations, continuous operation during upgrades, and automatic rollback capabilities in case of failures. This method ensures zero downtime and is particularly beneficial for organizations managing a large number of clusters.
