Netlify to Cloudflare SPA Migration

I currently host a React-based Single Page Application on Netlify and I’m ready to move it to Cloudflare Pages without a single minute of downtime. I need the entire migration handled end-to-end and documented so clearly that anyone on my team can repeat or roll back the process later... (Budget: $30 - $250 USD, Jobs: Cloudflare, Documentation, JavaScript, Netlify, Web Development)
