Moving servers from Co-Lo and want DNS to keep active when changing IP addresses
We are moving servers that host websites from a different provider to our data center. We will be changing the IP addresses of the hosted websites and want to know the best way to keep the DNS updated with minimal downtime during the transition.
Amazon Route 53 is the option of choice for managing our DNS. We mainly want to know if using an option like an Weighted record or Failover record is a good option or do we just need to add the new IP address to the A record?
