| = Performing an image-based upgrade on managed clusters at scale in one step | ||
|
|
||
| For use cases when service interruption is not a concern, you can upgrade a set of your managed clusters by using the `ImageBasedGroupUpgrade` CR with several actions combined in one step with one rollout strategy. | ||
| With one rollout strategy, the upgrade time can be reduced but you can only troubleshoot failed clusters after the upgrade plan is complete. | ||
|
|
||
| .Prerequisites | ||
|
|
||
| * You have logged in to the hub cluster as a user with `cluster-admin` privileges. | ||
| * You have created policies and `ConfigMap` objects for resources used in the image-based upgrade. | ||
| * You have installed the {lcao} and OADP Operators on all managed clusters through the hub cluster. | ||
