Legacy modernisation · Classic ASP

Move Classic ASP to .NET 8 with a React, Vue or Nuxt front end, de-risked by AI.

Classic ASP sites are tied to ageing Windows servers and code few people still read. Paradym Next reads the pages, includes and COM components, recovers the business logic and rebuilds it as .NET 8 Web APIs with a React, Vue 3 or Nuxt front end: in months, with your engineers approving every stage.

The problem

Classic ASP keeps your applications on infrastructure you want to retire.

Classic ASP mixes HTML, VBScript and database calls in the same files. It runs only on IIS and often depends on COM components installed on specific servers.

Infrastructure risk

Applications depend on legacy Windows Server builds that are hard to patch and cannot easily move to the cloud.

Security exposure

String-built SQL and hand-rolled authentication leave room for injection and other vulnerabilities.

No separation of concerns

Presentation, logic and data access are interleaved, so every change touches everything.

Hidden business rules

Business rules are spread across include files, session variables and inline SQL that nobody documented. They need to be recovered before the application can be safely rebuilt.

How it works

How our AI-powered modernisation engine works.

Four stages take your Classic ASP application from undocumented code to C# .NET 8 Web APIs with React, Vue 3 or Nuxt front ends in the cloud. AI agents do the reading, mapping, writing and testing. Your engineers approve every stage.

01

Automated discovery and code parsing

Next parses your ASP pages, VBScript includes, COM components, IIS configuration and SQL and extracts the business rules, data flows and integrations inside them. Every rule is traced to the code it came from, so nothing drifts in translation.

02

AI-assisted architecture blueprint

Agents map each module to clean target patterns: .NET 8 Web APIs, React, Vue 3 or Nuxt front ends, containerised hosting and managed SQL databases. Your architects review and approve the blueprint before any code is written.

03

Automated refactoring

From the approved blueprint, Next generates production-ready code for C# .NET 8 Web APIs with React, Vue 3 or Nuxt front ends in the cloud. It consolidates duplicated logic and removes dead code, and your engineers review every change.

04

AI-driven regression testing and validation

Generated test suites run the old and new systems on the same inputs, validating 99% functional equivalence before deployment. Any difference goes to your team to resolve.

Value acceleration

What AI acceleration changes.

Compared with a standard manual migration of your Classic ASP application.

Up to 40%

less development effort than a standard manual migration.

3–4x

faster upgrade and migration cycles.

Up to 60%

lower operational and cloud infrastructure overhead.

Risk and accuracy

AI does the heavy lifting. Your engineers make the decisions.

For a CTO or CIO, the risk in a rewrite is not speed but correctness. Human review is built into every stage, so AI output never reaches production unchecked.

Traced to source

Every extracted rule and generated module links back to the Classic ASP code it came from, so reviewers can check it line by line.

Human approval gates

Discovery, blueprint, code and release each need sign-off from your people. Nothing moves forward on AI output alone.

Equivalence testing

Old and new systems run the same test cases side by side, validated to 99% functional equivalence before deployment.

Governed AI

You choose which models are used and where they run, and every agent action is recorded for audit.
