[Pdns-users] 4.2 to 4.3 Authoritative Upgrade path

[Giovanni Vecchi]

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?

Thanks a lot

Thanks
