Semantic versioning¶
MSR uses semantic versioning. While downgrades are not supported, Mirantis supports upgrades according to the following rules:
When upgrading from one patch version to another, you can skip patch versions as no data migration takes place between patch versions.
When upgrading between minor releases, you cannot skip releases. You can, however, upgrade from any patch version from the previous minor release to any patch version of the subsequent minor release.
When upgrading between major releases, you must upgrade one major version at a time.
