How to Run Old and New CMS in Parallel
AdvancedQuick Answer
TL;DR
Running old and new CMS platforms in parallel means using a reverse proxy or CDN routing rules to direct traffic to the appropriate system based on URL path. Migrated sections serve from the new CMS; unmigrated sections continue from the old one. This requires careful URL routing configuration, consistent navigation across both systems, and clear editorial guidelines for which CMS to update during the transition period.
Key Takeaways
- Use a reverse proxy (Nginx, Cloudflare Workers) or CDN rules for URL-based traffic routing
- Maintain consistent navigation and design across both systems throughout the transition
- Establish clear editorial guidelines for which CMS to update during the parallel period
- Set a definitive cutover date — indefinite parallel running creates cost and complexity
