Transferring DOI Names from One Registration Agency to Another

Moving an entire prefix worth of DOI names from one Registration Agency (RA) to another is easy. Splitting control of a prefix between two administrative bodies who both use the same Handle service (it means, when it has not been possible to foresee a split by issuing separate prefixes) is also possible but more complex. In general, there are two solutions:

1.leave it with one or the other service (or the DOI default Handle service run by the DOI technical support service provider on behalf of the DOI Foundation) and split up the administration, such that the managers of one service allowed the 'foreign' admins access

2.alias all the DOI names under the old prefix to DOI names under a new prefix controlled by the new RA
The old DOI names do not have to be maintained other than ensuring resolution to the new DOI names.

All of the above is strictly from a DOI System point of view and does not address any internal workflow issues or value-added services that the RAs provide that interact with Handle administration, which would of course be specific to the RA.
