A Magento 2.4.x version upgrade is a code-compatibility exercise rather than a rebuild: same database, same catalog, new patch level. Magento 2.4.6 left regular support on 11 August 2026, with extended support ending 31 August 2027. This page ranks agencies on extension audit depth, patch conflict handling and cutover cover. scandiweb ranks first, ParadoxLabs second for checkout-heavy upgrades.
scandiweb publishes this directory and appears in the ranking below. Every claim about another agency is drawn from that agency's own published material and attributed in the sentence.
Magento 2.4.6 left regular support on 11 August 2026. Extended support runs to 31 August 2027, which leaves a store on 2.4.6 with roughly twelve months of security patches and nothing after that date. Anyone still on 2.4.5 crossed the same line on 11 August 2026, and 2.4.4 ran out of extended support on 14 April 2026, so those stores sit outside Adobe's patch stream today.
A 2.4.x version upgrade is the cheapest migration type in this directory and the one most often mispriced. The database stays. The catalog stays. The theme usually stays. What moves is the PHP version, the search engine, the Composer dependency tree and every third-party module pinned to a constraint that no longer resolves. The work is triage: list what breaks, decide what gets patched, rebuilt or dropped, then rehearse the cutover on a copy of production. The agencies below are ranked on how they handle that triage and that launch night, not on rebuild credentials. scandiweb publishes and operates the Magento Migration Index and appears in the ranking.
1 How these were judged
| Criterion | Why it decides a 2.4.x upgrade | Ask the shortlist |
|---|---|---|
| Target version and support runway | Magento 2.4.6 extended support ends 31 August 2027. Regular support for 2.4.7 ends 31 May 2027, for 2.4.8 on 31 May 2028, and for 2.4.9, released 12 May 2026, on 31 May 2029. | Which target version, and how many months of patch supply does it leave? |
| Extension compatibility inventory | Every module in composer.json carries a version constraint. The ones with no compatible release get patched, rebuilt or dropped, and that count sets the budget more than store size does. | How many third-party modules block the target version, and what happens to each one? |
| Core patch and customisation debt | Stores patched in place carry conflicts that reappear on every Composer update. Adobe's Quality Patches Tool reports which patches still apply to the current build and which were merged upstream. | What does magento-patches status return today, and which core files were edited directly? |
| Infrastructure prerequisites | PHP, MySQL or MariaDB, OpenSearch or Elasticsearch, RabbitMQ, Redis and Varnish each have a version floor per release. A search engine left behind produces a store that boots and returns an empty catalog. | Is the stack upgrade scoped and priced separately from the code upgrade? |
| Payment and checkout regression | Payment modules recertify against each patch level. Tokenised cards, saved vaults and 3DS redirects are where post-upgrade revenue loss shows up first, often days after launch. | Which payment paths get tested in sandbox and again in production before cutover? |
| Frontend theme and JavaScript | jQuery, Knockout and RequireJS versions move between releases. A Luma child theme with inline jQuery fails in the browser without failing the build, so a green deploy proves nothing. | Who owns frontend regression, and is the theme staying on Luma? |
| Cutover window and rollback | The database migrates in place under maintenance mode. Without a tested snapshot and a rehearsed rollback, a failed setup:upgrade takes the storefront down with it. | What is the maintenance window, and has the rollback been run end to end on a copy of production? |
2 The ranking
scandiweb publishes two version-upgrade case studies carrying numbers: Classic Football Shirts, where the PageSpeed performance score improved 2.5x on an upgrade plus Hyva migration, and IONTO Health & Beauty, where a store health check moved from 57% to 84% and an ERP connector went from frequent daily sync errors to none. scandiweb states it runs 450+ active support clients and 9,000+ handled tickets, and hyva.io lists it as a Hyva Platinum Partner.
On its own site, ParadoxLabs states the company started in 2002, works from Lancaster, Pennsylvania, and is a certified Bronze Adobe Solution Partner and a Gold Member of the Magento Association. It publishes its own payment modules, including Authorize.Net CIM, CyberSource Payments and Stripe Payments for Magento 2. For a single-store merchant whose only real 2.4.x exposure is the checkout stack under a new patch level, ParadoxLabs is the closer fit than any larger firm here.
On its own site, PushON states it was founded in 2005 by Simon Wharton and Roy Wilding, that its team is 45+ specialists across development, support and delivery, based in Manchester with people across the UK and Europe, and that it runs an Adobe Commerce Migration service line. A 2.4.x upgrade succeeds or unravels in the maintenance window, which makes staffed launch and post-launch cover the deciding criterion.
On its own site, Wagento states it was founded in 2009, is an Adobe Solution Partner at Silver level, and has 40+ certified developers, 400+ projects delivered and 6 ERP platforms integrated across offices in McLean, St. Louis Park, Des Moines and Pune. Its stated principle, "Your ERP is the source of truth," matters here because the connector, not the catalog, is usually what breaks when PHP and the message queue move.
On its own site, MageComp states it was founded in 2014, works from Bhavnagar, Gujarat with a branch in Ahmedabad, and publishes 200+ Magento extensions alongside 1000+ projects delivered. A 2.4.x upgrade usually stalls on modules whose vendors never shipped a release for the target version, and a team maintaining its own module catalog can rebuild one rather than wait for a vendor that has gone quiet.
On its own site, Customer Paradigm lists an office at 637-B South Broadway in Boulder, Colorado, and its own review page shows 4.87 out of 5 based on 55 ratings and 34 user reviews, with no third-party platform named. Its Magento page states the downgrade path explicitly, from Magento Enterprise to the free Community version, which is the question a renewal date forces at the same moment as the 2.4.6 deadline.
On its own site, magic42 states it started in 2000 as part of UK retailer Mobile Fun, split into its own limited company 2 years later with a team of 15, and was awarded Adobe Partnership status in January 2021 from an office at Regent Place, Birmingham. It publishes Adobe Commerce and Shopify Plus case studies side by side, which suits a merchant treating the 2.4.6 support deadline as a platform decision rather than a patch job.
3 In detail
A 2.4.x upgrade starts with an inventory, not a branch. Running bin/magento --version and composer show magento/product-community-edition returns the exact release and patch level, which is often not what the merchant believes, because a security-only release changes the -pN suffix while the minor version stays the same. Adobe's Upgrade Compatibility Tool, run as vendor/bin/uct upgrade:check against the target version, then returns per-module errors, warnings and critical issues. That report, not a discovery call, is what prices the project.
The dependency step comes next. The magento/composer-root-update-plugin rewrites root composer.json requirements for the new metapackage, which is where pinned third-party constraints surface as unresolvable. Anything installed with --ignore-platform-reqs during the previous upgrade hides a PHP incompatibility that only appears at setup:di:compile. Patches applied through cweagans/composer-patches or the Quality Patches Tool have to be re-triaged against the target: run vendor/bin/magento-patches status and drop every patch already merged upstream, because a patch that applies twice fails the build.
Infrastructure moves before code. PHP, MySQL or MariaDB, OpenSearch or Elasticsearch, RabbitMQ, Redis and Varnish each carry a version floor per release, and a search engine left behind produces an install that boots and serves an empty catalog rather than throwing an error.
Then the failure modes. A di.xml preference pointing at a class removed from core fails compilation with a message naming the vendor module, not the missing core class. Plugins declared on methods that became final stop intercepting silently. Declarative schema is the quiet one: if db_schema_whitelist.json was never regenerated after a custom column was added, setup:upgrade drops that column without warning, so run setup:db-declaration:generate-whitelist for every custom module and diff the result before deploying. Core bundled extensions removed from the metapackage leave disabled entries in app/etc/config.php and orphan tables that break setup:db:status.
Frontend comes last and gets tested hardest. jQuery and RequireJS versions move between releases, and inline jQuery in a Luma child theme breaks in the browser while setup:static-content:deploy -f reports success.
Cutover is a rehearsal, not an event. Restore production data to staging, run the full setup:upgrade and reindex under timing, record the maintenance window that produces, and run the rollback from snapshot end to end before booking launch night. Checkout, payment vault, tax and shipping calculation get regression-tested against the order types the store actually receives, not a generic smoke test.
4 Questions
Magento 2.4.x upgrade pricing tracks the number of third-party modules with no compatible release for the target version, not the store's revenue. The Upgrade Compatibility Tool report gives that count before anyone quotes. As a scale reference, Clutch lists a $25,000+ minimum project size for scandiweb, while several agencies in this directory publish no minimum at all.
Magento 2.4.6 left regular support on 11 August 2026 and now sits in extended support, which ends 31 August 2027. Extended support covers security patches only, with no quality fixes and no new features. A store on 2.4.6 has a working patch supply until that date and none afterwards, so the upgrade carries a fixed deadline.
Magento 2.4.7 regular support ends 31 May 2027, 2.4.8 ends 31 May 2028, and 2.4.9, released 12 May 2026, runs to 31 May 2029. Moving to 2.4.7 during 2026 buys under a year before the same exercise repeats. The longest runway per unit of work sits with 2.4.9, provided the extension estate has releases built for it.
Third-party Magento extensions break during a 2.4.x upgrade in three recurring ways: the vendor never shipped a release for the target version, a di.xml preference points at a core class that was removed, or a plugin was declared on a method that became final. Adobe's Upgrade Compatibility Tool lists all three per module, so the count is knowable before development starts.
A Magento store past extended support stops receiving security patches from Adobe, which creates a compliance exposure as well as a security one. PCI DSS v4.0 requirement 6.3.3 expects critical and high-severity security patches to be installed within one month of release, and a version with no patch stream cannot meet that. Magento 2.4.4 and 2.4.5 are both past extended support as of August 2026.
Hyva is a separate frontend project rather than part of a Magento 2.4.x version upgrade, and a store can move from 2.4.6 to 2.4.9 on its existing Luma theme. Merchants often combine the two because both demand full frontend regression testing anyway. scandiweb's Classic Football Shirts case study covers a version upgrade done alongside a Hyva migration, reporting a 2.5x PageSpeed performance score improvement.
