Our Expertise
Signs You Need to Upgrade Your Store
Outdated Magento 2
version
Adobe stopped releasing security patches for Magento 2.4.5 and below. Your store is exposed to known vulnerabilities with no official fix on the way.
Broken Extensions After
New Updates
Third-party developers build for the latest Magento versions. Fall too far behind, and conflicts start showing up across your store.
Slow Storefront
Newer Magento versions have performance improvements built into the core. If standard fixes haven't worked, the platform version is likely the problem.
Missing features
Every Magento release adds new built-in functionality. Staying behind means paying for third-party extensions to do what the latest version does out of the box.
Maintenance Time
Older versions accumulate technical debt. If your team spends more time on workarounds than on new features, an upgrade changes that.
Platform Fit
What’s New in the Latest Magento Version
500+ Bug Fixes
Over 500 quality fixes across checkout, payments, catalog management, GraphQL, and admin UI, meaning fewer workarounds for your development team and a more stable store overall.
PHP 8.5 Support
Adds PHP 8.5 compatibility and drops support for PHP 8.2. Running on an older version means your server stack is falling behind and creating future compatibility risks.
Valkey 8.x Replaces Redis
Valkey 8.x is now the default cache backend, replacing Redis. A key compatibility consideration for any store running custom caching configurations.
OpenSearch 3.x Support
OpenSearch 3.x is now the recommended search backend, replacing OpenSearch 2.x. Stores on older search configurations will need to account for this as part of any 2.4.9 upgrade.
Core Architecture Rebuilt
Three foundational framework components replaced: the MVC layer, the caching system, and the admin content editor. Deep infrastructure changes that improve long-term stability and reduce technical debt.
17 Security Fixes
Critical vulnerabilities patched including arbitrary code execution and privilege escalation risks. CAPTCHA now enforced on REST and GraphQL account creation endpoints.
Payment Upgrades
New local payment methods for European and Latin American markets, Google Pay vaulting, auto-updated saved cards, and promo code support on Apple Pay and Google Pay express checkout flows.
Modern Stack
Symfony updated to 7.4 LTS, MySQL 8.0 and MariaDB 10.6 replaced with newer LTS versions. A modern, well-supported infrastructure foundation.
3-Year Support
Magento 2.4.9 is supported through approximately May 2029, giving you a stable long-term foundation to build on.
Our Magento Version Upgrade Services
Magento 1 to Magento 2 Migration
Magento 1 reached end-of-life in June 2020. If your store is still running on it, you're operating without security patches, without official support, and with extensions that are no longer being maintained. We move you to Magento 2 with your data, customizations, and functionality intact.
- Full data migration including products, orders, and customer history
- Custom module and theme rebuild for Magento 2 compatibility
- Post-migration testing and performance validation
Adobe Commerce Cloud Upgrade
Adobe Commerce Cloud upgrades involve additional complexity around cloud infrastructure, pipelines, and environment configuration. Our team handles the full process including PHP, Elasticsearch, and database compatibility.
- Cloud environment audit and upgrade planning
- PHP, MySQL, and Elasticsearch version upgrades
- Post-upgrade monitoring and issue resolution
Magento 2 Upgrade Services
Running Magento 2.3 or an older 2.4 version means missing security patches, performance improvements, and new features that Adobe has already shipped. We upgrade your store to the latest version without disrupting your live operations.
- Compatibility audit of extensions and custom code before upgrade
- Staging environment upgrade and full QA before going live
- Zero downtime deployment to production
Security Patch Installation
Not ready for a full version upgrade? We install the latest security patches on your current version to close known vulnerabilities and keep your store protected while you plan a full upgrade.
- Security patch assessment and compatibility check
- Staging environment testing before live deployment
- Documentation of all changes applied

Why Businesses Trust Klizer?
Audit Before Anything
Else
We don't start upgrading until we fully understand your store. Every engagement starts with a free audit covering your version, extensions, custom code, and server stack so there are no surprises mid-project.
300+ eCommerce Projects Delivered
We've handled upgrades across stores of every size and complexity, from straightforward version bumps to full Magento 1 to Magento 2 migrations with custom modules and ERP integrations.
Zero Downtime
Upgrades
Every upgrade is executed in a staging environment first. We deploy to production only after full QA sign-off, with a rollback plan ready in case anything unexpected surfaces.
Data & Integrations, Preserved
Upgrades done wrong lose data, break custom code, and disrupt integrations. We handle compatibility fixes before the upgrade goes live so your store comes out the other side working exactly as it should.
Post-Upgrade Support Included
Our job doesn't end at go-live. We monitor your store after the upgrade and resolve any issues that surface quickly, so you're not left on your own after the most critical part of the process.
