We are planning on changing our NameServers to point to Cloudflare tomorrow.
Currently we have a web based security product protecting our website and we want this to be replaced with cloudflare.
Our CNAME records www point to this product.
What do i need to do to our DNS to ensure zero downtime and maintain our security?
I’ve setup the security policies already as best i can before the NameServer change so this is purely a DNS question.
