CaaS Upgrade Backward Compatibility

This section provides information on the compatibility of pre-upgrade and post-upgrade management/workload clusters after VMware Telco Cloud Automation when upgraded to VMware Telco Cloud Automation 3.1.1.

Annotate Details

Type	Means	Example	Comment
Yes	Supported	Support upgrade cluster
No	Not supported (Ready-only)	When the management cluster is in an intermediate version that cannot be paused, such as v1.25.7 or v1.27.5, support for upgrading workload cluster is not available.
NA	Can not proceed	When the workload cluster is already at the highest supported version, support for upgrade is not available.
	Not available on UI	For a classy single node workload cluster, node-pool section will not be on the UI. Some parts will be hidden too.

Management Clusters Compatibility

For management clusters, the following table lists the cluster compatibility.

Attention:

The VMware Telco Cloud Automation Manager (TCA-M) and VMware Telco Cloud Automation Control Plane (TCA-CP) are mandatorily upgraded to 3.1.1. The management cluster just support V1 version.

Workload Cluster Compatibility Cluster Operations

The following table lists the cluster compatibility for workload clusters

Attention:

Management cluster is mandatory to upgrade from v1.24.10 to v1.25.7 and v1.26.8 to v1.27.5, final upgrade to v1.28.7. All workload clusters are V2 workload cluster, V1 workload cluster has been deprecated in TCA 2.3.0. These tables show the workload cluster compatibility for multi management cluster kubernetes version.
