Moving years of content from WordPress to a new CMS is a real risk — and "will it actually work?" is a better question than most migration guides bother to answer honestly. This post maps exactly what carries over cleanly, what needs manual work, and what won't move at all, so you can decide whether an afternoon or a full rebuild is in your future.
EmDash's plugin sandbox — the feature that keeps a rogue plugin from quietly reading your entire database — only works on Cloudflare. Everything else runs fine on a VPS, Docker, Vercel, or AWS. That one tradeoff is worth understanding before you pick a deployment path.
Every WordPress plugin you install gets unrestricted access to your database, your files, and your admin panel — by design, not by accident. That's not a bug from 2003 that got patched; it's still how WordPress works today, and it's why 91% of WordPress vulnerabilities traced back to plugins in 2025. EmDash was built to change that relationship at the architecture level, not the policy level.
Most WordPress security problems don't come from bad passwords or weak servers — they come from plugins that have full access to your site the moment you install them. Cloudflare built EmDash to fix that at the architecture level, and it just launched in beta.
Hosting a personal blog on AWS instead of Cloudflare Workers can cost you $30/month before you've served a single visitor — because AWS charges a ~$16 load balancer fee just to keep the lights on. For EmDash sites, that gap only grows once egress fees kick in. Here's exactly what each platform costs at every traffic level.
"AI-native CMS" is on every landing page in 2026 — but strip away the marketing and most products are just a chatbot stapled to decade-old infrastructure. EmDash, Cloudflare's open-source CMS, takes a different approach: the AI integration is built into the protocol layer itself, not added on top.
Migrating from WordPress to EmDash still requires real work — but one part, historically the most tedious, can now be handed off to an AI agent. Here's exactly what it handles, and where you'll still need to step in.
Hosting operators keep asking when AI content management will be "ready to ship" — with EmDash, it already is. The CMS launched in April 2026 with a native MCP server built in, meaning Claude or GPT-4o can create, edit, and manage content directly without custom middleware or glue code. Here's exactly how to connect them in under five minutes.
