//edit From DUDB functions ( just change %s.dudb.sav to %s.sav :P )
stock udb_Exists(nickname[]) {
  new tmp[MAX_STRING];
  format(tmp,sizeof(tmp),"%s.sav",udb_encode(nickname));
  return fexist(tmp);
}

First you need use udb_Exists to check that username available or not

//edit From DUDB functions ( just change %s.dudb.sav to %s.sav :P )
stock udb_RenameUser(nickname[],newnick[]) {
  new oldfname[MAX_STRING];
  new newfname[MAX_STRING];
  format(oldfname,sizeof(oldfname),"%s.sav",udb_encode(nickname));
  format(newfname,sizeof(newfname),"%s.sav",udb_encode(newnick));
  return frenametextfile(oldfname,newfname);
}

After, use udb_RenameUser to rename file have info oldname to newname
