Headless CMS Migration Case Study: Sanity + Next.js Website & AI Content Platform

Modern websites are no longer just collections of pages. They increasingly need to support marketing campaigns, SEO, landing pages, blogs, structured business information, AI assistants, multiple channels, and frequent content updates.

Murmu Software Infotech experienced this challenge directly.

Our previous website used Next.js with custom .NET APIs and an internally developed administration layer. While technically functional, even small content changes frequently required developer involvement. Marketing and content teams could not move at the speed needed for publishing, SEO, campaigns, and ongoing website growth.

We therefore migrated our own production website to a headless architecture using Sanity and Next.js, transforming the website from a developer-driven publishing system into a structured content and AI-ready digital platform.

The Challenge: Developers Were Part of Every Content Update

Before the migration, routine website updates could take approximately 2–4 hours.

A seemingly simple change could involve communicating requirements to a developer, updating backend structures or content, testing the change, deploying it, and verifying the result.

The custom administration system also had limited flexibility for evolving content requirements.

As our website expanded across services, case studies, blogs, offers, industries, SEO landing pages, and dynamic experiences, this model created increasing friction.

The central problem was not Next.js itself.

The problem was that content and application logic were too closely connected.

Marketing needed greater publishing independence, while developers needed to focus on product engineering rather than routine content maintenance.

The Solution: Sanity as the Structured Content Layer

We redesigned the architecture around Sanity as the content platform while continuing to use Next.js for the frontend experience.

The new model became:

Sanity CMS → Structured Content → GROQ → Next.js → Website / Digital Experiences

Website content was migrated into structured Sanity schemas instead of being embedded inside custom APIs or page-specific administration logic.

This created reusable content models for areas such as:

• Service pages
• Blog articles
• Case studies
• FAQs
• Calls to action
• SEO metadata
• Business information
• Reusable website sections

Sanity’s Content Lake stores content as structured, queryable data, while GROQ allows applications to request precisely the content required for each experience.

Faster Editorial Workflows

One of the most visible improvements was publishing speed.

The previous workflow often required hours for relatively small updates. After migration, many routine content changes could be created and published within seconds or minutes, depending on the update.

This significantly reduced routine developer dependency.

Content and marketing teams could update copy, metadata, sections, articles, and other structured content directly through the CMS rather than placing every change into the development queue.

Modern Sanity + Next.js architecture also supports live content updates and visual editing workflows where editors can preview changes and connect rendered content back to the corresponding Studio fields.

Next.js Remained the Experience Layer

Migrating to a headless CMS did not mean replacing the frontend technology.

Next.js remained responsible for rendering the public website.

This separation allowed us to keep full development control over UI, components, routing, responsive behavior, technical SEO, integrations, and application functionality while giving content teams independent control over structured information.

GROQ queries retrieve only the required content from Sanity, keeping the relationship between content and frontend components explicit and maintainable.

This architecture also gives us a stronger foundation for caching, revalidation, live content, and future frontend evolution. Sanity’s official Next.js tooling supports these patterns directly.

Building an AI-Ready Content Architecture

The migration created another important opportunity: our website content became structured knowledge that could be consumed beyond the website itself.

Our AI chatbot was moved toward a CMS-driven architecture and connected with MCP-based content access so it could use current structured website information as part of its knowledge workflow.

This is strategically important.

Instead of maintaining one knowledge source for the website and another manually prepared knowledge base for AI, structured CMS content can become reusable context for:

Website → Search → AI Assistant → Content Automation → Future Agents

Sanity now officially supports MCP access for AI tools as well as Content Agent capabilities for analyzing, creating, updating, and working with schema-aware content.

The migration therefore evolved from a CMS project into an AI-ready content operations architecture.

Stronger SEO and Content Structure

The previous case study claimed the migration improved SEO performance. Without publishing before-and-after organic-search measurements for this migration specifically, a more accurate conclusion is that the new architecture created a stronger SEO operating foundation.

Structured fields can now independently manage titles, descriptions, FAQs, internal content relationships, reusable metadata, and other search-focused information.

This makes SEO improvements easier to implement without modifying frontend code for every editorial change.

Business Impact

The migration changed how our teams operate.

It:

• Reduced routine content-update time from hours to seconds/minutes
• Reduced developer involvement in ordinary publishing
• Created reusable structured content
• Improved collaboration between development and marketing
• Established a more flexible SEO content model
• Connected website knowledge with AI-oriented workflows
• Created a foundation for future content automation and personalization

Most importantly, the website is no longer simply a frontend connected to an administration system.

It has become a structured digital content platform capable of serving humans, search engines, applications, and AI systems from the same content foundation.
