Serialization of version information can be done in the same way as normal serialization by serializing the subtree below /jcr:system/jcr:versionStorage. The special status of these nodes with respect to versioning is transparent to the serialization mechanism.
The serialized content of the source version storage can be deserialized as “normal” content on the target repository, but it will not actually be interpreted and integrated into the repository as version storage data unless it is integrated into or used to replace the target repository's own version storage.
Methods for doing this kind of “behind the scenes” alteration to an existing version storage (whether based on the serialized version storage of another repository, or otherwise) are beyond the scope of this specification.
