Legacy Deluxe has a Renumber RINs option, which can also renumber the MRINs, but any custom numbering should be done using a User ID for either the Individual or Marriage. When renumbering the RINs/MRINs in the Deluxe Edition, you can renumber a current RIN/MRIN to another number, fill in missing RINs/MRINs from a specific number or fill in from all missing RINs/MRINs When selecting to change to a specific RIN/MRIN, only numbers are accepted. The User IDs can be shown on views, lists, reports and web pages in lieu of or along with the RINs/MRINs. User IDs can be any combination of alpha, numeric or symbol. In the free Standard Edition, the only option for renumbering RINs/MRINs is during an export to a new Family File. Changes to the RINs/MRINs take place throughout the database so there is no problem with linked items getting "lost".
