Migration
Gatsby to Next.js Migration
Move off Gatsby maintenance risk onto Next.js App Router — keep your CMS, preserve rankings, and give editors a modern preview workflow.
Focused rescue sprints · often 4–10 weeks
Gatsby sites that still work in production are increasingly expensive to keep alive: dependency rot, slow builds, and a shrinking talent pool. The goal of a Gatsby to Next.js migration is not a redesign for its own sake — it is a controlled frontend swap that keeps your CMS and SEO equity intact.
We have years of production Gatsby delivery (Builder.io marketing sites, Strapi association sites, large commerce fronts) and have moved clients onto Next.js where App Router, ISR, and Vercel/AWS hosting are a better long-term fit. The rescue playbook prioritizes URL parity, CMS adapters, and Core Web Vitals.
If your Gatsby site is stuck on an old major version, failing CI, or blocking marketing launches, a Next.js migration is usually faster than fighting the old toolchain — especially when the content model in Builder.io, Strapi, or Contentful is already sound.
What you get
- Next.js App Router frontend with typed CMS fetch layers
- Parity for routes, metadata, and structured data
- Draft preview / visual editing reconnected to the CMS
- Faster builds and clearer hosting on Vercel or AWS Amplify
- Documented handoff for the team maintaining the site

Migration process
- 01
Stack inventory
Map Gatsby plugins, data sources, and page creation APIs to Next.js equivalents — App Router routes, generateStaticParams, and revalidation strategy.
- 02
CMS adapter
Reuse Builder.io, Strapi, Contentful, or WordPress as the content source. Rebuild query layers once so pages stay thin and typed.
- 03
Parity pass
Match URLs, redirects, OG tags, and JSON-LD. Diff critical templates against production so the migration does not quietly drop SEO fields.
- 04
Cutover
Ship behind a staging URL, verify preview and forms, then cut DNS with a rollback path. Post-launch: Search Console and Core Web Vitals checks.
FAQ
- Can we keep Builder.io or Strapi when leaving Gatsby?
- Yes — that is the preferred path. The CMS stays; only the React frontend and data-fetching layer move to Next.js. Visual editing and draft preview are reconnected as part of the migration.
- Is this a full redesign?
- Not by default. Many Gatsby to Next.js migrations rebuild the same design system on App Router for speed and maintainability. A visual refresh is optional and scoped separately.
- What about Gatsby v2 to v5 upgrades instead?
- Sometimes a Gatsby upgrade is enough. When the team wants App Router, Vercel primitives, or a longer-lived React stack, Next.js is usually the better investment — we help you choose during discovery.
