Migrate an MKE cluster to a new OS¶
MKE supports the use of a Node-replacement strategy in migrating an active cluster to any supported Linux OS.
Migrate manager nodes¶
When migrating manager Nodes, Mirantis recommends that you replace one manager Node at a time, to preserve fault tolerance and minimize performance impact.
Promote the new Node to an MKE manager and wait until the Node becomes healthy.
Repeat the previous steps until all manager Nodes are running the new OS.
Migrate worker nodes¶
It is not necessary to migrate worker Nodes one at a time.
