Planning a Move to Next.js

Start here if the first question is how to move a legacy platform or older front end to Next.js safely. This is Next.js migration consulting for the architecture, route, content, and release decisions that decide whether the move holds up.

Choose the right Next.js migration path when an older front end, legacy platform, or hard‑to‑maintain site needs a cleaner architecture and safer migration plan.

Common situations

  • Replacing a legacy SPA, CMS front end, or hard‑to‑maintain site with Next.js.
  • Modernising an existing Next.js codebase to newer routing patterns.
  • Preserving URLs, content operations, and search visibility during migration.

Choose the source platform or migration shape that is closest to the current estate.

Choose the closest scenario

  1. Scenario

    React SPA to Next.js Migration

    Move a React SPA to Next.js before client‑rendered routes keep important pages out of search and start capping performance or delivery speed.

  2. Scenario

    WordPress to Next.js Migration

    Move a WordPress‑led front end to Next.js when speed, scale, and maintainability all need to improve without losing URLs, preview trust, or editorial continuity.

  3. Scenario

    Gatsby to Next.js Migration

    Move off Gatsby before slow builds, brittle plugins, and awkward content updates start blocking delivery.

  5. Scenario

    Drupal to Next.js Migration

    Move a Drupal‑led estate to Next.js without losing aliases, preview behaviour, or SEO continuity on content‑heavy routes.
