Have you moved your domain names?

We bought a new domain name and I registered it within Cloudflare for DNS and management. Cloudflare's website and options seem miles better than network solutions.
I'm considering moving our other domains from network solutions over to Cloudflare too.
Any drawbacks with this? Doesnt seem to be any downtime related as long as dns records match on both sides.
Not sure on cloudflares pricing as far as renewals yet though.
