Description

Issue JCR-669 introduced a global namespace index. this is used by some persistence managers in order to
keep the serialization of names small (fewer bytes).

unfortunately this forms a problem when a workspace needs to be migrated to another repository with other namespace indexes. so an easy migration is not possible unless you export/import the entire workspace using system view (which is almost impossible for huge workspaces).

another potential problem is cause by the global data store, since all workspaces share the same.
so when migrating a workspace, you would need to transfer all respective records in the datastore to the target repository.

where the datastore problem can be solved by copying the respective items, the namespace indexes are a bigger problem, since the serialized items need to be adjusted.

suggest to alter the bundle pm to use the 'name index' for the namespaces as well.
