I’d like to move an existing site to Cloudflare, but want to be sure I don’t break things on the way.
It looks like by default if I switch my nameservers to Cloudflare, all my DNS records are updated to immediately push all traffic via Cloudflare, which I don’t want.
Am I right in thinking that the least invasive way of incrementally switching over is to first change Proxy Status to DNS Only on all my DNS records, perform the nameserver switch, and then try enabling Proxied on, eg, my staging subdomain?
Anything else I should check beforehand? Is there a way of only proxying 10% of traffic, for instance?
