Hi Rubens, Please see below.

Does this need to be a one-to-one mapping listed all contacts, or for registries that can say a general rule can it be just the rule ? For instance, something like "all ROIDs previously known as something-something will now be something_something-UniqueID". Either would work. A description of the algorithm would be preferred, but if not possible or for simplicity (e.g., there are only a handful of names registered when the ROID change is done) the registry provides a table mapping one to one, that would work too.
