I will upgrade and migrate your legacy nextjs, react websites
Ishmam Rahman
About this gig
Is your Next.js or React app stuck on an old version, slow, or full of deprecated dependencies? I'll bring it current safely, without breaking your functionality, data, or SEO.
I'm a senior full-stack engineer with 5+ years of production experience, including leading a Next.js 12 to 16 migration on a 7-year-old platform while preserving all database models and content.
What's included:
- Major/minor version upgrades (Next.js, React, Node.js)
- Fixing breaking changes & deprecated APIs
- Dependency cleanup & security patches
- Performance optimization (Core Web Vitals, bundle size)
- Pages Router to App Router migration
- Full backup before any changes
Why work with me: real production experience (not just tutorials), clear communication, and everything tested before handover not just "it compiles."
Message me your current version and approximate site size, and I'll recommend the right package.

FAQ
Will my data and content be safe during the migration ?
Yes. I always create a full backup of your existing codebase and data before making any changes, and test thoroughly before handing the project back to you.
Which versions can you migrate from and to ?
I work with any Next.js or React version, from older releases up to the latest stable release. Send me your current version and I'll confirm the upgrade path.
What do you need from me to get started ?
Access to your code repository (GitHub/GitLab/Bitbucket), or a zip of your project, plus any staging/dev environment details if available. No production access is required upfront.
Can you migrate from the Pages Router to the App Router ?
Yes, this is included in the Standard and Premium packages. I'll evaluate your current routing structure and let you know what to expect before starting.
What happens if something breaks after delivery ?
All packages include testing before handover, and Premium includes 14 days of post-launch support for any issues that surface after going live.
My app is larger than your package limits, can you still help ?
Yes, message me with your page/route count and I'll quote a custom scope before you order.
Will you also add new features while upgrading ?
This gig focuses on safely upgrading your existing app. If you'd like new features added too, message me first so we can scope that separately.
