We will migrate our recursive DNS resolver servers to a recent version on new servers.
The servers will keep their IP-Addresses and therefore no configuration change on systems relying on those name-servers for DNS lookups is needed.
We don't expect this change to cause any harm (due to having a redundant pair of nameservers), for the sake of safety we perform the switch-over during our maintenance-window.
This change only affects recursive DNS resolution. Our authoritative DNS servers (name servers) used for domains are not affected.
