Versioning is vital to avoid breaking reports or models when metric definitions change.

Store the semantic layer configuration as code (e.g., YAML or JSON) in a source control system.

Use branches or feature flags to introduce new metrics and test them before promoting to production.

Communicate changes to stakeholders and provide migration paths when formulas or names evolve.

Many platforms support multiple semantic layer versions coexisting, allowing old reports to run while new definitions are tested.

MageMetrics treats the semantic model as a code asset, integrates with Git and offers diff tools to review changes.
