Magento Upgrade or Replatform: How to Decide

What changed since this was first written

The 2022 version of this article gave seven reasons to choose Magento. That question now has its own page, Magento's strengths and weaknesses, so this one answers the question owners of an existing store are actually asking: keep going on Magento, or leave.

The question has dates attached now. Adobe's lifecycle policy (checked 30 October 2026) gives each release line three years of standard support from its release date, with one extra year for 2.4.6 and 2.4.7. It also says that from 1 June 2027 Adobe will stop maintaining Cloud environments on unsupported versions, up to and including suspending their traffic.

The newest release line is 2.4.9, published on the Magento 2 releases page on 12 May 2026 alongside security patches for 2.4.8 and 2.4.7.

Which Magento versions are still supported?

Adobe publishes these dates for Adobe Commerce, the licensed edition. Magento Open Source ships on the same release lines, so the sensible reading for an Open Source store is to treat the same dates as its own. Anything older than 2.4.4, and every Magento 1 store, is already past all of them.

The server software has its own clock. Adobe's policy notes that PHP 8.1 reached end of life on 31 December 2025 and PHP 8.2 does on 31 December 2026, and it flags both as a risk to PCI compliance for the older release lines that use them.

Four ways forward, compared

Read across the last two columns and one thing stays constant. Whichever row you pick, the links between the store and your other systems need attention, and they are the part most upgrade and migration plans leave until the week before launch.

Five questions that settle it

• Which release line are you on? Check it in the admin footer or with your developer. On 2.4.6 or older, the decision has a deadline; on 2.4.8 or 2.4.9, you have time to choose properly.
• Do you still use what Magento is for? Several storefronts, many product attributes, customer group pricing and B2B ordering are hard to recreate elsewhere. If you use none of them, you are paying for capacity you do not need.
• How many extensions does the store run? Every one has to be compatible with the new line, so a store with dozens faces a bigger upgrade than one with a handful.
• Who will maintain the store afterwards? A Magento store needs a Magento developer for every future upgrade. If you do not have one, that is an argument for a lighter platform.
• What does the store connect to? An ERP, warehouse system or CRM integration adds work to every option, and a replatform means rebuilding all of it.

If the platform comparison is what is holding you up, what moving between Magento and WooCommerce involves covers the data, password and redirect work in detail.

The part that breaks: integrations

A Magento store rarely runs alone. Orders go to accounting, customers go to a CRM, stock comes from a warehouse or ERP, and each of those links depends on the store's API, its extensions and the shape of its data.

An upgrade can change any of the three. An extension that fed orders to the CRM may be replaced with one that sends different fields, and a custom module may stop firing the event an integration listened for. Nothing errors on screen; orders simply stop arriving at the other end.

A replatform removes the question of compatibility and replaces it with a rebuild. Every connection has to be built again against the new platform's API, which is why connecting Magento to an ERP and which Magento jobs need an extension and which need an integration are worth reading before either move.

Integrations built outside the store, in Make, n8n or a small service of their own, survive both moves better than ones built as store extensions, because only one end of them changes. Zapier, Make and n8n compared covers which tool suits which order volume. That is the workflow automation we build, and the customer record it feeds is designed during CRM setup and management.

A sequence that keeps the store selling

1. List every connection. Write down each system the store sends data to or receives it from, what moves, and how often. This list is the test plan.
2. Cut extensions first. Remove any extension the store no longer uses before the upgrade or migration starts, so there is less to make compatible or replace.
3. Build the new version beside the old one. Run the upgraded or new store on a staging copy, with its integrations pointed at test accounts rather than live ones.
4. Test a full order end to end. Place an order, pay, refund it and change stock, then confirm each step arrived in every connected system with the right fields.
5. Watch the first weeks after launch. Failures in integrations surface days later, when a report does not add up. Monitoring that alerts on a failed run catches them first, which is what our automation maintenance covers.

Where AI fits

AI helps with the slowest parts of an upgrade or migration without replacing the people doing it. It can read a custom module and draft the changes a new release line needs, and it can propose the field mapping between two platforms from their exports.

Both are first drafts for someone who knows the systems, not finished work. A wrong field mapping produces orders that look right and carry the wrong tax or customer group, which is exactly the kind of error that survives testing.

After the move, an assistant that can look up live order status answers the "where is my order" emails that spike whenever a store changes. That is an integration rather than a widget, and it is the kind of build our AI automation work covers.

Common questions

Which Magento versions does Adobe still support?

As of October 2026, Adobe lists 2.4.9 and 2.4.8 on standard support, 2.4.7 on standard support until 31 May 2027, and 2.4.6 on extended support until 31 August 2027. Versions 2.4.4 and 2.4.5 receive security fixes only until 31 May 2027, and anything older is unsupported.

Is it cheaper to upgrade Magento or move to Shopify?

It depends on the store. An upgrade is usually smaller when the store has few extensions and still uses Magento's features; a move is often cheaper over several years when the catalogue is modest, because the upgrades stop. Either way, budget for rebuilding or retesting every integration.

What happens if I stay on an unsupported version?

The store keeps working, but it stops receiving security fixes, and an unsupported PHP version puts PCI compliance at risk. On Adobe Commerce on Cloud, Adobe says that from 1 June 2027 it may suspend traffic to environments running unsupported versions.

Will my integrations survive a Magento upgrade?

Often, but never assume it. Extensions that are replaced or updated can change the data they send, and custom code can stop firing the events an integration relies on. Test a full order, refund and stock change through every connected system before launch.

Can you keep our store connected through an upgrade or move?

Yes. We map every connection before the work starts, rebuild or retest each one against the new version or platform, and monitor them after launch, using Make, n8n or custom API work. Each project is quoted once we know your systems (how automation projects are priced explains why), so tell us what your store connects to and we will tell you where the risk is.
