If the street names were added by people who have not agreed to the license change, you cannot legally use that information for re-mapping. This is probably the case with most street names that were removed during the license change process.
There may be some exceptions (e.g. a street mapped and named by someone who has agreed, which was removed only because it used pre-existing nodes by non-agreers), but these are likely quite rare in comparison.
