How to Migrate a Legacy PHP Site to Next.js Without Losing SEO

The Fear of Migration

Most businesses stay on WordPress/PHP because they fear the "Migration Dip". We have executed over 50+ migrations with zero traffic loss.

The Strategy

1. Inventory Everything: Crawl your current site to map every URL.
2. 301 Mapping: Create a strict 1-to-1 redirect map.
3. Incremental Rollout: Use Nginx to serve the new Next.js app for specific routes while keeping the old PHP site as a fallback.
