Cloudflare Pages Zero Downtime Migration

Developers Cloudflare Pages
1

Hello! If my DNS is not hosted on Cloudflare, how does one move their application to Cloudflare Pages without incurring downtime?

There is no “TXT” verification record that I can find, either in the Pages UI or the pages add_domain api response (https://developers.cloudflare.com/api/operations/pages-domains-add-domain), or any option to upload a custom SSL cert beforehand. Not having a zero downtime migration is kinda disappointing, as this is something Netlify and Vercel both offer out of the box (eg: https://vercel.com/guides/zero-downtime-migration).

Is there something I’m missing in the Cloudflare Documentation, or is this just not a supported feature at this time? If it is not supported, is this something at least on the roadmap? I see that other Cloudflare products support this https://developers.cloudflare.com/cloudflare-for-platforms/cloudflare-for-saas/domain-support/hostname-verification/, so it doesn’t really seem like an unfair request.

Can’t you just swap out the CNAME and add it as a custom domain in Cloudflare Pages at the same time?

You have to set the CNAME in your DNS provider, then verify in Cloudflare, then Cloudflare needs a moment to generate the SSL cert. I can’t ask every team at my company to just have 30 seconds of down-time in the middle of the day, and it would be highly preferable to not keep people up at midnight to switch DNS.
