LEGACY TECH

We've seen it all. We can fix it.

A reference list of legacy technologies we modernize — and what the recommended migration path typically looks like.

Frontend Frameworks

AngularJS (1.x)
Critical
End of life since 2021. No security patches. Migration to Angular 17+ or React.
jQuery-heavy frontends
High
Hard to maintain, no component model. Migration to modern component-based UI.
Backbone.js
High
Abandoned, unmaintained. Full rewrite in modern stack recommended.
Knockout.js
High
Still used in enterprise, but no active development. Migration path available.
Ext JS legacy versions
High
Complex but migratable — we've done it.
Vue 2
Medium
End of life since 2023. Migration to Vue 3 or React is typically smooth.
Old React (class components, Redux)
Medium
Functional components and modern patterns significantly improve maintainability.

Backend Technologies

PHP 5 / PHP 7
Critical
PHP 5 is end of life. PHP 7.4 ended support in 2022. Migration to PHP 8.x.
.NET Framework (4.x)
High
Not cross-platform, limited new features. Migration to .NET 8 LTS recommended.
Java 8 / Spring Boot 1.x
High
Java 8 security patches ended. Migration to Java 21 LTS + Spring Boot 3.
Ruby on Rails 4.x / 5.x
High
Multiple CVEs unpatched. Upgrade to Rails 7.x or re-platform where appropriate.
Old Laravel (5.x, 6.x)
High
End of life. Migration to Laravel 11 is well-trodden — we do it often.
Node.js / Express legacy
Medium
Unstructured Express apps accumulate debt fast. Refactor + add TypeScript.
Outdated Python 2 / Django 2
Critical
Python 2 EOL since 2020. Migration to Python 3.12+ with modern tooling.

Architecture & Systems

Monoliths with high coupling
High
We don't automatically break them into microservices — often a modular monolith is the right target.
Systems without tests
High
We establish test safety nets before any refactoring begins.
SOAP / XML-based integrations
Medium
Migration to REST/GraphQL APIs with proper documentation.
Old CRM/ERP/intranet platforms
High
Custom portals built on old CMSes or frameworks — we assess and recommend migration or replacement.
Spreadsheet-driven operations
Medium
Replace with purpose-built internal tools. This is where AI automation shines.
Deployment without CI/CD
High
Manual deployments are a safety risk. We introduce CI/CD as part of any modernization.
IMPORTANT NOTE

We present this as a business problem, not a tech checklist.

Old technology isn't a problem in itself. It becomes a problem when it makes your business slower, riskier, or more expensive to operate. We help you understand the real cost of your current stack — and then modernize it in a way that creates business value, not just newer version numbers.
