Release Compatibility Matrix¶
The Release Compatibility Matrix describes the cloud configurations that have been supported by the product over the course of its lifetime and the path a MOSK cloud can take to move from an older configuration to a newer one.
For each MOSK release, the document outlines the versions of the product major components, the valid combinations of these versions, and the way every component must be updated or upgraded.
For a more comprehensive list of the product subcomponents and their respective versions included in each MOSK release, refer to Release Notes, or use the Releases section in the Container Cloud UI or API.
Compatibility matrix¶
The following table outlines the compatibility matrix of the most recent MOSK releases and their major components in conjunction with Container Cloud and Cluster releases.

The product support status reflects the freshness of a MOSK cluster and should be considered when planning the cluster update path:
- Supported
Latest supported product release version to use for a greenfield cluster deployment and to update to.
- Deprecated
Product release version that you should update to the latest supported product release. You cannot update between two deprecated release versions.
The deprecated product release version becomes unsupported when newer product versions are released. Therefore, when planning the update path for the cluster, consider the dates of the upcoming product releases.
Greenfield deployments based on a deprecated product release are not supported. Use the latest supported release version for initial deployments instead.
- Unsupported
Product release that blocks automatic upgrade of a management cluster and must be updated immediately to resume receiving newest product features and enhancements.
- 1(1,2,3,4,5,6,7,8)
Mirantis Container Cloud will update itself automatically as long as the release of each managed cluster has either supported or deprecated status in the new version of Container Cloud.
A deprecated cluster release becomes unsupported in one of the following Container Cloud releases. Therefore, we strongly recommend that you update your deprecated MOSK clusters to the latest supported version.
- 2(1,2,3,4,5,6,7,8)
The LTS duration of an OpenStack version is two years. For support timeline for different OpenStack versions, refer to OpenStack support cycle.
- 3(1,2,3,4,5,6,7,8)
The kernel version of the host operating system validated by Mirantis and confirmed to be working for the supported use cases. Usage of custom kernel versions or third-party vendor-provided kernels, such as FIPS-enabled, assume full responsibility for validating the compatibility of components in such environments.
Cluster update paths¶
Cluster updates in MOSK encompass both management cluster and managed cluster updates.
Management cluster update¶
Management cluster update is performed automatically as long as the release of each managed cluster has either supported or deprecated status in the new version of Container Cloud. In case, any of the clusters managed by Container Cloud is about to get an unsupported status as a result of an update, the Container Cloud updates will get blocked till the cluster gets to a later release.
For the cluster release statuses, see Container Cloud documentation: Cluster releases (managed).
Managed cluster update to a major version¶
Major cluster update is initiated by a cloud operator through the Container Cloud UI. The update procedure is automated and covers all the life cycle management modules of the cluster that include OpenStack, Tungsten Fabric, Ceph, and StackLight. See Cluster update for details.
Version-specific considerations
Before the MOSK 24.1 series, if between the major releases you apply at least one patch release belonging to the N series, you should obtain the last patch release in the series to be able to update to the N+1 major release version.
Since MOSK 24.1.5, the product introduces a new approach to cluster updates. For details, refer to Cluster update scheme and Update schemes comparison.
Managed cluster update to a patch version¶
Patch cluster update is initiated by a cloud operator through the Container Cloud UI. The update procedure is automated and covers all the life cycle management modules of the cluster that include OpenStack, Tungsten Fabric, Ceph, and StackLight. See Update to a patch version for details.
Version-specific considerations
Since MOSK 24.1.5, the product introduces a new approach to cluster updates. For details, refer to Cluster update scheme and Update schemes comparison.

The table below provides the schema for the cluster update between the latest and upcoming releases for MOSK clusters.
