Sentry's Migrations and Re-platforming service moves websites, hosting, automation and data onto a modern owned stack — standard CMS to headless, hosting to Cloudflare's edge, Zapier or Make to self-hosted n8n, legacy databases to governed data — as a controlled, reversible cutover rather than a rebuild.

Legacy platforms, sprawling SaaS bills and fragile databases quietly tax speed, cost and security. We migrate you to a modern, owned stack — standard to headless, onto Cloudflare's edge, off per-task automation, and onto clean governed data — as a controlled, reversible cutover, not a risky rebuild.

## What it does

Re-platforms websites, hosting, automation and data onto a modern, owned stack — standard→headless, →Cloudflare edge, Zapier/Make→n8n, and legacy→governed databases — via a controlled, reversible cutover.

## Where it creates value

Removes structural drag from the whole value stream at once: faster surfaces, lower run-cost, fewer dependencies and trustworthy data — so every downstream service compounds on a cleaner foundation.

## Why it cannot be ignored

Legacy stacks compound their cost every year — licence fees, slow pages, per-task automation bills and fragile data. Staying put means paying more each quarter for less speed, less security and less control.

## What you get

- **Controlled & reversible** — Map current → required, migrate in parallel, then cut over staged with rollback ready — never a big-bang gamble.
- **Faithful by default** — Content, data, integrations, SEO and redirects carried across with care — you keep what works.
- **Cheaper to run** — Edge hosting, self-hosted automation and a clean data layer cut licence, hosting and per-task costs.

## Questions and answers

### How do you migrate without losing our search rankings?

Content, data, integrations, SEO and redirects are carried across deliberately rather than recreated. The current state is mapped to the required state first, so the redirect map is built from what actually exists — the single most common way a migration loses rankings is discovering the old URLs after the switch, not before.

### What happens if the migration goes wrong on the day?

It is designed so that it can be undone. Sentry migrates in parallel and cuts over in stages with rollback ready, rather than running a big-bang switch. A migration that cannot be reversed is a gamble regardless of how well it was planned.

### What exactly gets migrated?

Four things, together or separately: a standard CMS to headless; hosting to Cloudflare's edge; per-task automation on Zapier or Make to self-hosted n8n; and legacy or fragile databases to a clean governed data layer. Most re-platforming projects fail because only one of the four moves and the others keep taxing the result.

### Why not just stay on what we have?

Because legacy stacks compound their cost every year — licence fees, slow pages, per-task automation bills and fragile data. Staying put means paying more each quarter for less speed, less security and less control. The decision is not migrate versus nothing; it is migrate versus an increasing bill.

### Will migrating actually reduce what we spend?

That is a large part of the point. Edge hosting, self-hosted automation and a clean data layer cut licence, hosting and per-task costs, which is why the saving is modelled in the Financial Value Model before the work is committed to rather than claimed afterwards.

### How do we know a migration is worth doing at all?

The free Discovery session and Financial Value Model produce fourteen structured commercial outputs, including what the current stack costs to keep and what the migration would return. If the numbers do not support moving, that is a legitimate outcome of Discovery.
