DNS Only system requirements

We have a couple of very old DNS-only VPSs that are running CentOS 5. These need to be upgraded, probably to CentOS 7 to futureproof themselves. They only run BIND. They only have 512MB of RAM, but continue to hum along just fine. Can DNS-ONLY be installed on a CentOS 7 VPS with just 512MB of RAM? I'm just trying to get a general idea of how to plan to upgrade these servers.

  Hello, 512MB should be suitable if you are only using it to serve DNS Zones. You can use the "--force" flag when beginning the installation to bypass the memory requirements:
  sh latest-dnsonly --force
  Let us know if you have any additional questions. Thanks!
