Why Migrations Need a Specialist

CMS migrations have more moving parts than they appear. Here's what's at stake.

Data Integrity: Migrations risk corrupting or losing content. Every document, reference, and asset is validated before, during, and after the move.
Zero Downtime: Your content operations don't stop for a migration. Careful planning and staged execution keep your team productive throughout.
Schema Confidence: Schema changes compound in complexity. A clear migration plan prevents drift, preserves editorial workflows, and avoids breaking your front end.

Migration Services

Every migration is different. Here are the areas I specialize in.

Content Migration

Move content between Sanity projects or from another CMS into Sanity. Document types, references, images, and files — all mapped, transformed, and validated.

Cross-project data transfer
CMS-to-Sanity imports
Asset migration and rewriting
Reference integrity checks

Schema Migration

Restructure and evolve your Sanity schemas without losing data. Rename fields, reshape documents, split or merge types — with scripts that are repeatable and auditable.

Document type splitting/merging
Portable Text transforms
Repeatable migration scripts

Platform Migration

Moving to Sanity from another CMS, or consolidating multiple Sanity projects. Full-stack migration planning from content modeling through front-end integration.

How It Works

A structured process that keeps your team informed and in control.

Discovery

We start with a call to understand your current setup, content model, and goals. No commitment — just clarity on what the migration involves.

Migration Audit

I review your schemas, data, and integration points to produce a detailed migration plan — including scope, risks, and timeline.

Execution

The migration runs in stages with validation at each step. Scripts are repeatable, so nothing is a one-shot operation.

Verification & Handoff

Content is verified against the source, your team reviews the results, and I hand off documentation so you own the process going forward.

What the work looks like

Scripted, repeatable, and auditable.

Every migration runs through versioned scripts — not one-shot operations. Each change is reviewable, re-runnable against staging, and safe to roll back.

import { client } from "./sanity.client";

// Move legacy `authorName` into a structured `author` object
const posts = await client.fetch(
  `*[_type == "post" && defined(authorName)]`
);

const tx = client.transaction();

for (const post of posts) {
  tx.patch(post._id, (p) =>
    p.set({ author: { name: post.authorName } })
     .unset(["authorName"])
  );
}

await tx.commit({ visibility: "async" });
