Coming from Drupal? We move to Go, with AI.

Drupal 7 at end of life, a move to Drupal 10 that looks like a full rewrite: if everything has to be redone anyway, you might as well land on something lean. I move your content, taxonomies and access rights to a Go site.

What we keep, what we leave.

We don't copy Drupal into Go: we keep what matters to you and leave the rest behind.

We keep

Everything that matters to you.

content and its fields
taxonomies and vocabularies
users, roles and permissions
views and listings, rebuilt as pages
URL aliases (pathauto)
language versions

We leave behind

Everything that costs you.

the overpriced Drupal 7 to 10 migration
abandoned contrib modules
PHP, the database and the cache to look after
a back office nobody likes

Watch points · Drupal

What I watch closely.

Views are reviewed one by one: every useful listing becomes a page, the rest disappear.
Role-based permissions are reproduced and tested: private content stays private.
Pathauto aliases are kept unchanged; old node/123 URLs are redirected.

Six steps, zero downtime.

a typical migration

clh --inventory drupal
  ✓ every URL, every piece of content, every plugin
clh --read --ai
  ✓ rule map, reviewed with you
clh --go --tests
  ✓ every old page = a test to pass
clh --migrate --data
  ✓ replayable scripts until the day before
clh --compare old new
  ✓ zero diff, or an intended one
clh --cutover && clh --handover
  ✓ live, and you hold the keys

01
Record everything.
I record everything that exists on your Drupal: every public URL, every piece of content, every plugin and what it really does, the forms, the accounts. That record is the reference until the very end.
02
Have AI read the code.
AI agents read what exists (theme, plugins, settings, custom code) and extract the real rules: who sees what, which price applies when, which email goes out after what. I review that map with you: it becomes the reference, not the old code.
03
Write Go, tests first.
Tests before code: every page of the old site becomes a case to reproduce. The new site is written in Go by agents I run in parallel, and every line goes through me before it's kept.
04
Move the data.
Content, media, accounts and history are moved by replayable scripts: the copy is rerun as often as needed, right up to the day before cutover. Personal data never goes through the AI.
05
Compare, side by side.
Both sites run together. A robot compares them page by page: content, titles, links, prices. We fix until the difference is zero, or intended.
06
Cut over, then hand over the keys.
Cutover at DNS level, with no downtime; the old site stays read-only until you're sure. You get the source code, the documentation and the access: you don't depend on me.

AI speeds it up. I decide.

AI does in hours what used to take weeks: reading, comparing, writing the repetitive code. It doesn't choose the architecture, and it puts nothing into production without me.

What AI does

The volume.

read thousands of lines of code and settings in hours
draft the map of business rules
write the repetitive code and the tests
compare the old and new sites, page by page

coding agents · in parallel

What I do

The decisions.

decide the architecture
settle with you what stays and what goes
review and approve every line
own security and production

27 years in production

What you gain.

One stack less

--go

PHP, the database, the cache and the contrib modules: all of it leaves production. What remains is one compiled program that starts in a fraction of a second.

ProofThis page is served by a Go program I wrote, the same one that runs clh.do and clh.agency.

Fewer machines

--sobre

A Go service takes millions of requests a day on a modest machine: the hosting bill and the power draw go down together.

Fewer holes

--durcir

No third-party plugins, no weekly emergency update: the attack surface shrinks to what you actually use.

ProofFor content sites I designed NADAPROD, open source: I import your existing site, and every page becomes a self-contained file. No database, no plugins, no trackers, no third-party calls.

Faster

--ms

Pages served in milliseconds: your visitors stay, and search engines notice.

Yours

--cles

Source code, documentation, access: it's all yours. You depend on no vendor, no plugin marketplace, and not on me.

Your questions.

Drupal 7 is no longer maintained: is it urgent?

It has had no official security fixes since January 2025: every new flaw stays open. I can lock it down for the duration of the migration.

We're a public institution with accessibility requirements.

The HTML is rewritten cleanly, without generated layers: a chance to aim for WCAG instead of suffering it.

Will my search rankings suffer?

Not if things are done in the right order: every existing URL is recorded before anything is touched, then kept as is or redirected with a 301. Titles, descriptions and structured data follow. And a faster site ranks better, not worse.

Who edits the site afterwards?

You do. Depending on how you work: text files you edit like a document, or an admin interface written for what you actually do, without the hundred menus you never use.

What does the AI see of my data?

The code, the structure and anonymised samples. Your customers' personal data (accounts, orders, addresses) is not sent to the models: it is moved by scripts, on your servers or mine.

How long does it take, and what does it cost?

It depends on the volume and the features to reproduce. After the inventory you get a firm scope, schedule and quote. AI cuts the time spent writing code sharply: that's what makes a tailor-made rewrite affordable today.

What if I want to go back?

The old site stays in place, read-only, until you're sure. The cutover happens at DNS level: going back takes a few minutes.

Do you host it afterwards?

If you like, on my machines or at datamix.io. Otherwise the binary runs at any Linux host: the code and the access are yours.

Coming from elsewhere?
