// en / magento upgrade — audit from EUR 450

A Magento upgrade rarely kills the shop.
It kills one store view.

The site comes back up and looks fine. A week later one market has been quoting the wrong tax, or half a catalogue stopped showing in one country. That is why we start with a compatibility audit and test every store view separately — not just the default one.

This upgrade is for you if...

You are on 2.4.6 or older
The line is running out of security support and every month adds patches you will not receive. The longer you wait, the bigger the jump and the more modules fall out along the way.
You inherited the codebase
A shop taken over from a previous agency, or built over years by different people. Core modifications, unlicensed modules, an overridden theme — the audit tells you what survives the upgrade before anything moves.
You run multistore with B2B pricing
Several store views, customer-group pricing, country restrictions. These are exactly where an upgrade breaks quietly and only surfaces when a customer complains.
You integrate with an ERP
SAP, Dynamics, Comarch, a custom API. A version jump can move the data contracts underneath you. We check that before, not after.
// what you get

What the EUR 450 audit covers

// proof
SISL scanner result for demo-magento.sisl.pl: technical SEO warnings and missing analytics
sisl.pl/en/scanner, 18 September 2026 — our own demo store. We run the same public scanner on your store before quoting an upgrade: exposed files, security headers, technical SEO, CrUX performance. No login, ~30 seconds.
// process

Four steps, no surprises halfway.

01
Access (day 1)
Read-only SSH to production or a copy, composer.lock, the output of bin/magento module:status, the database schema, repository access. NDA signed first if you need one.
02
Audit (days 2-5)
Environment inventory, module and custom-code review, integration mapping. Output: a PDF report plus a fixed-price quote for the build.
03
Staging and upgrade (weeks 2-3)
A copy of production on separate infrastructure, the upgrade, module and dependency updates, environment configuration. You get a staging link and test alongside us.
04
Go-live and rollback window (weeks 3-4)
Backup, deployment outside selling hours, smoke tests on production. The window in which a rollback stays safe is agreed in writing beforehand.

Frequently asked

Why a Polish studio?

Central European rates, an EU timezone that overlaps your working day, and the people doing the work on the call rather than an account manager between you and them. We run Magento day to day — Hyvä, B2B, multistore, ERP integrations. Being based in Poland is a pricing and timezone advantage, not a limitation.

Is the price fixed or hourly?

Fixed at both stages. The audit is a flat EUR 450 and the build gets a single figure once the audit is done. Hourly, at EUR 45, applies only to work outside the agreed scope — and always against an estimate you approved beforehand, never after the fact.

What if a module has no compatible version?

Three routes, in this order: update to a compatible release if the vendor shipped one, replace it with an equivalent including data migration, or repair and rewrite it on our side. The audit says which route applies to which module and what it costs. The choice stays yours.

Can we roll back if production breaks?

Yes, within an agreed window. In practice that means a database dump and a filesystem snapshot taken immediately before deployment. Be aware that after a point, orders placed on the new version start blocking a rollback — that is data consistency, not technique. We fix the length of that window in writing before go-live.

What about module licence costs?

Those are yours and we count them during the audit. Moving to a build compatible with the new Magento line often needs an active vendor subscription — Amasty, Mageworx, Mirasvit and similar. It is a common nasty surprise mid-project, so we price it before anything starts.

What access do you need for the audit?

Read-only SSH to production or a copy, composer.json and composer.lock, the output of bin/magento module:status and setup:db:status, a database schema dump (data is not needed and can be anonymised), repository access or an archive of app/code and app/design, server specifications and a list of external integrations.

Is the audit mandatory?

Yes, and we treat it as a condition. We do not take on an upgrade quoted blind — that is the single most common reason these projects run fifty percent over budget. If you already have a recent audit from someone else, we will happily quote from it.
