## Concepts

- All Buckets on MinIO are always in one of the following states: unversioned (the default) and all other existing deployments, versioning-enabled, or versioning-suspended.

        boolean changed = false;

        if (metadata != null && reference != null) {
            Versioning versioning = metadata.getVersioning();
            Versioning versioningRef = reference.getVersioning();
            if (versioning != null && versioningRef != null) {
                String lastUpdated = versioning.getLastUpdated();
                String now = versioningRef.getLastUpdated();

                changed = true;
            }
        }

        Versioning versioning = sourceMetadata.getVersioning();
        if ( versioning != null )
        {
            Versioning v = getVersioning();

                changed = true;
            }

Note that objects with `null` versions, i.e. objects created prior to enabling versioning break the immutability guarantees provided by versioning. When existing object replication is enabled, these objects will be replicated as `null` versions to the remote targets provided they are not present on the target or if `null` version of object on source is newer than the `null` version of object on target.
