Upgrade Considerations
Before you upgrade to MKE 4k, confirm the existence of a backup of your MKE 3 cluster and review the Back up MKE disaster recovery documentation for MKE 3.
ℹ️
The Swarm cluster and all associated artifacts are not included in the upgrade from MKE 3 to MKE 4k.
Back up all non-MKE components separately, making sure to check both manager and worker nodes, as these are at risk of being deleted rather than migrated during the upgrade to MKE 4k.
