Reasons Why You Should Upgrade Magento 2 to Latest Version

A Magento 2 upgrade moves your Adobe Commerce or Magento Open Source installation from an older 2.x release to a newer one — for example, from 2.4.5 to 2.4.7 or the newly released 2.4.8. Each release ships security patches, PHP compatibility changes, performance improvements, and new built-in features. Unlike a Magento 1 to Magento 2 migration (which rebuilds the platform from scratch), a version upgrade keeps your existing codebase intact while updating the core. Stores on the latest supported release load up to 50% faster, process more concurrent checkouts, and stay within Adobe's quarterly security patch window.

A client came to us last year running Magento 2.4.3-p3. The store was "stable" — no visible issues, orders flowing, team happy. Then Adobe dropped security patches for that branch entirely, their hosting company flagged a PHP 7.4 deprecation warning, and a routine PCI scan surfaced two medium-severity vulnerabilities with no available fix. That's when the conversation shifted from "do we need to upgrade?" to "how quickly can we do it?"

That situation is not unusual. A lot of merchants delay Magento upgrades because the store is running fine and the risk of change feels higher than the risk of staying put. The problem is that "running fine" and "secure" are two different things once you're on an EOL version.

Below we break down the actual reasons to upgrade — not just the generic "better performance" talking points, but the specific things that matter to your store, your team, and your bottom line.

Where Does Your Store Stand Right Now?

Before anything else, it helps to know what version you're on and whether it's still receiving patches. Here's the current support schedule as of May 2025:

To find your current version, go to Admin → System → About Magento, or check bin/magento --version via CLI. If you're on 2.4.4 or below, you're already in unpatched territory.

The Security Argument Is the Simplest One

Magento releases security patches on a quarterly cycle. The moment your version hits end-of-life, that cycle stops for you. Any CVEs disclosed after that date — and there are always new ones — get patched for supported versions only.

The practical risk isn't theoretical. Magento stores on EOL versions are actively targeted by automated scanners that probe for known vulnerabilities. The Magento Security Scan Tool (available free at account.magento.com) will flag your version as a risk factor within weeks of your support window closing.

On top of that, payment card compliance (PCI DSS 4.0) now requires that platforms stay within their vendor's active support lifecycle. If your acquirer or payment processor audits you and finds you're running EOL Magento, that's a compliance finding — not just a technical one.

Performance: What Actually Changes in Newer Versions

The "faster performance" line gets used a lot without specifics. Here's what's actually different in Magento 2.4.6 and 2.4.7 compared to earlier releases:

• Async indexing for inventory and price: In older versions, catalog price rule updates or bulk inventory changes would lock the indexer and slow the storefront. 2.4.6+ handles these asynchronously via the message queue, keeping the frontend responsive during admin operations.
• GraphQL caching improvements: If you run a headless or PWA frontend, the resolver-level cache in 2.4.7 is significantly more granular — reducing uncacheable queries that previously caused full page regeneration.
• Elasticsearch/OpenSearch upgrade: 2.4.7 supports OpenSearch 2.12 and Elasticsearch 8.x. The newer search stack handles large catalogs (100K+ SKUs) with noticeably faster faceted navigation.
• Varnish 7 compatibility: Older Magento versions had partial support. 2.4.7 is fully tested against Varnish 7, which has improved edge-side includes and better handling of stale-while-revalidate scenarios.

These aren't marginal improvements. For a store processing 500+ orders a day, async indexing alone removes a whole category of admin-caused frontend slowdowns.

The Checkout Has Been Rebuilt — and It Shows

Magento's checkout has historically been one of its weaker points — too many steps, too much JavaScript blocking render, and a cart abandon rate that frustrates merchants. Starting in 2.4.6, Adobe began a systematic rebuild of the checkout module.

In 2.4.7, the default checkout includes native Apple Pay and Google Pay support via Braintree (no custom extension required), improved guest checkout that no longer forces account prompts mid-flow, and a redesigned address step that reduces form fields through intelligent address lookup integration.

None of this is available on 2.4.4 or 2.4.5. If your checkout conversion rate hasn't budged in 18 months, part of that may simply be that you're running a checkout UI that Adobe itself has now deprecated.

Adobe Commerce's AI Features Require a Current Version

If you're on Adobe Commerce (the paid edition), staying on older versions means you're locking yourself out of Adobe Sensei GenAI — the product recommendation and live search engine that Adobe has been investing heavily in since 2023. These features are cloud-delivered, but they require the underlying Magento version to be within the active support window to receive configuration updates and API compatibility patches.

For Magento Open Source users, the benefit is less direct but still real: the REST and GraphQL API surface in 2.4.7 is substantially more complete than in 2.4.4, which makes it easier to integrate third-party AI tools, recommendation engines, and personalization platforms without custom module development.

Your Extensions Are Probably Being Left Behind Too

This is the one that catches merchants off guard. Third-party extension vendors (including MageAnts) release updates regularly — bug fixes, security patches, compatibility improvements. Most of these updates require Magento 2.4.6+ to install.

When you're on an old Magento version, you eventually find yourself unable to update an extension because its latest version has a Magento version constraint that excludes you. So you stay on an older extension version. Then that extension has a bug or a security issue, and the vendor's response is "update to the latest version" — which you can't do without first upgrading Magento.

It snowballs. After a couple of years on an old version, many stores are running 10–15 extensions that are 2–4 versions behind their current release. That's a significant accumulated technical debt that makes every future change more expensive.

What a Magento 2 Upgrade Actually Involves

The "just run composer update" perception of Magento upgrades is roughly as accurate as "just update WordPress." It works for small standard stores. For anything with custom code, multiple extensions, or significant order volume, there's a process:

Total timeline for a standard upgrade (one version jump, 10–20 extensions, modest custom code): 10–15 business days. Stores with heavier customization or multiple version jumps should budget 3–5 weeks.

Things to Sort Out Before You Start

A few things will make or break your upgrade timeline, so it's worth understanding them upfront:

• Extension compatibility is usually the longest part. Not all vendors move fast. If you have extensions that haven't had a release in 12+ months, check whether they're still maintained before you schedule the upgrade.
• Custom code that calls deprecated Magento core classes directly (common in older stores) needs to be refactored. The upgrade compatibility tool flags these, but someone has to fix them.
• If you're more than one major version behind (e.g., on 2.4.3 and targeting 2.4.7), plan for a sequential upgrade path through intermediate versions — the database migrations require it.
• Your hosting environment needs to support the target PHP version. If you're on shared hosting that only offers PHP 8.1, upgrading Magento to 2.4.8 before the hosting is updated will fail.
• Don't schedule the upgrade within 6 weeks of your peak sales season (Black Friday, Ramadan, etc.). Regardless of how well the upgrade goes, you don't want to introduce change at your highest-risk period.

Why Merchants Work With MageAnts for Upgrades

We've been doing Magento upgrades since 2.0 was in beta. Our team is Adobe Commerce certified, and we've worked through enough edge cases — multistore setups, complex custom checkout flows, unusual hosting environments — to know where upgrades tend to go sideways.

What we've found matters most to merchants: clear communication on scope before work starts, no surprises mid-project, and someone available post-go-live when production inevitably surfaces something the staging environment didn't. Our upgrade projects include a 30-day support window after launch for exactly that reason.
