I suppose that gets into questions about programs explicitly using 
utmpname.  If a program using the old symbol versions called utmpname 
explicitly with some filename, that's probably the name of a file in the 
old format.  But if it doesn't call utmpname, either you can access the 
old files in the old format and not get current data, or the new files in 
the new format and convert.
