Downtime

The Challenge

A digital media company publishing 50+ articles per week had outgrown WordPress. Their site loaded in 8+ seconds on mobile, plugins conflicted constantly, and the editorial team hated the clunky editing experience. SEO rankings were tanking because Core Web Vitals were in the red. A failed migration attempt 6 months prior had left the team terrified of trying again.

Our Solution

We executed a seamless zero-downtime migration from WordPress to Next.js with Sanity as the headless CMS.

Content Migration to Sanity CMS

Built a Python migration script that transferred 4,200+ articles, 12,000 images, author profiles, categories, and SEO metadata from WordPress to Sanity — preserving every URL slug, redirect, and internal link for zero SEO disruption.

Next.js Frontend on Vercel

Rebuilt the entire frontend in Next.js 14 with ISR (Incremental Static Regeneration). Articles load in under 1 second with perfect Lighthouse scores. Implemented structured data markup for rich snippets and a custom reading progress bar.

Editorial Workflow in Sanity Studio

Customized Sanity Studio with real-time collaboration, scheduled publishing, SEO previews, and an AI-powered headline analyzer. Editors can preview articles exactly as they'll appear on the live site before publishing.

Zero-Downtime Cutover Strategy

Used Vercel's edge network for a gradual rollout — 10%, 25%, 50%, 100% of traffic over 4 days. Monitored Core Web Vitals, 404 rates, and SEO indexing at each stage. Not a single minute of downtime.
