Multi-cluster update in Azure Kubernetes Fleet Manager provides you the ability to orchestrate upgrades to your clusters in a planned manner across multiple clusters to achieve a consistent environment across the set of clusters.
As an example, you can group your clusters into different environments such as development, staging, and production. After you have established the grouping, you can then chain these clusters together sequentially in an update run.
This feature is currently in public preview.
