Hi Peter, thanks for your quick reply. If 4.2 queries do not ask for that field, I can't figure out what could go wrong, isn't it? Otherwise, what's the best upgrade path for this scenario? May I need to stop every powerdns instance -> upgrade database schema -> upgrade every powerdns instances -> start powerdns instances?
