The CMS alternatives page lists systems with very different editing and delivery models. Start with the content model, not the homepage appearance.
Migration sample
- Move an article, landing page, reusable component, image, and translated entry.
- Rebuild roles, editorial review, scheduling, revisions, and preview.
- Verify canonical URLs, redirects, metadata, feeds, and search indexing.
- Export all content, assets, and relationships; inspect whether formats are usable elsewhere.
- Measure routine editing effort and upgrade or hosting burden.
Preserve author attribution and old links through cutover. A theme can be recreated; lost content relationships and revision history are harder to repair.
