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. The mono label marks the risk of staying on it.

Frontend frameworks

[ Critical ]

AngularJS (1.x)

End of life since 2021. No security patches. Migration to Angular 17+ or React.

[ High ]

jQuery-heavy frontends

Hard to maintain, no component model. Migration to modern component-based UI.

[ High ]

Backbone.js

Abandoned, unmaintained. Full rewrite in modern stack recommended.

[ High ]

Knockout.js

Still used in enterprise, but no active development. Migration path available.

[ High ]

Ext JS legacy versions

Complex but migratable — we've done it.

[ Medium ]

Vue 2

End of life since 2023. Migration to Vue 3 or React is typically smooth.

[ Medium ]

Old React (class components, Redux)

Functional components and modern patterns significantly improve maintainability.

Backend technologies

[ Critical ]

PHP 5 / PHP 7

PHP 5 is end of life. PHP 7.4 ended support in 2022. Migration to PHP 8.x.

[ High ]

.NET Framework (4.x)

Not cross-platform, limited new features. Migration to .NET 8 LTS recommended.

[ High ]

Java 8 / Spring Boot 1.x

Java 8 security patches ended. Migration to Java 21 LTS + Spring Boot 3.

[ High ]

Ruby on Rails 4.x / 5.x

Multiple CVEs unpatched. Upgrade to Rails 7.x or re-platform where appropriate.

[ High ]

Old Laravel (5.x, 6.x)

End of life. Migration to Laravel 11 is well-trodden — we do it often.

[ Medium ]

Node.js / Express legacy

Unstructured Express apps accumulate debt fast. Refactor + add TypeScript.

[ Critical ]

Outdated Python 2 / Django 2

Python 2 EOL since 2020. Migration to Python 3.12+ with modern tooling.

Architecture & systems

[ High ]

Monoliths with high coupling

We don't automatically break them into microservices — often a modular monolith is the right target.

[ High ]

Systems without tests

We establish test safety nets before any refactoring begins.

[ Medium ]

SOAP / XML-based integrations

Migration to REST/GraphQL APIs with proper documentation.

[ High ]

Old CRM/ERP/intranet platforms

Custom portals built on old CMSes or frameworks — we assess and recommend migration or replacement.

[ Medium ]

Manual data flows between core systems

Point-to-point exports and hand-carried files between ERP, CRM and reporting. We replace them with monitored, automated integrations.

[ High ]

Deployment without CI/CD

Manual deployments are a safety risk. We introduce CI/CD as part of any modernization.

Important note

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.

One call, an honest read on risk and effort — before any commitment.
