ASP.NET Zero

ASP.NET Zero Migration & Modernization

Move your ASP.NET Zero application from AngularJS 1.x and ASP.NET MVC 5 to the latest Angular and ASP.NET Core, planned in stages and tested against the system you run today.

Migration & Modernization

From AngularJS to the Latest Angular, Step by Step

A structured path from an existing system to a current, supported architecture, typically prompted by an outdated framework version such as AngularJS, accumulating technical debt, dependencies that are no longer maintained, or new business requirements the current codebase can't accommodate cleanly.

Assessment

Inventory AngularJS screens, services and data.

Planning

Map each module to Angular and ASP.NET Core.

Module Migration

Rebuild screens in Angular, module by module.

Testing

Compare each screen's behavior with the original application.

Release & Support

Go live, then keep Angular and .NET up to date.

Migration Paths

What We Migrate

Most ASP.NET Zero migrations we are asked about start with an AngularJS front-end. Here is how each part of an older application moves to a current, supported stack.

01Front-End Migration

AngularJS 1.x to the Latest Angular

Early ASP.NET Zero projects were delivered on ASP.NET MVC 5 with an AngularJS 1.x front-end. AngularJS reached the end of its long-term support in December 2021, so it no longer receives security fixes, and modern libraries, browsers and developer tools have moved on.

We rebuild the AngularJS front-end in the latest Angular release, using TypeScript, components and Angular’s current tooling, so your application lines up with the Angular front-end that ASP.NET Zero ships today.

Controllers and $scope logic rewritten as typed Angular components and services.
Where it suits the application, AngularJS and Angular run side by side during the move, so users keep working.
Permissions, localization and tenant features are carried over and checked screen by screen.

02Back-End Migration

ASP.NET MVC 5 to ASP.NET Core

The AngularJS editions of ASP.NET Zero ran on ASP.NET MVC 5 and the .NET Framework. We move the server side to ASP.NET Core on current .NET, so the back-end and the new Angular front-end are both on supported versions.

Business logic, application services and data access are moved in planned stages, with data migration handled as part of each stage rather than at the end.

03Platform Migration

Other Applications onto ASP.NET Zero

Applications built outside ASP.NET Zero, for example on Web Forms, older MVC, or a custom framework, can be moved onto ASP.NET Zero to gain its ready-made multi-tenancy, user and role management, settings, audit logging and layered architecture.

We review what the system does today, then map its features and data onto ASP.NET Zero’s structure and the latest Angular front-end.

What This Covers

What ASP.NET Zero Migration Covers

Legacy Architecture Assessment

Reviewing the current system's structure, AngularJS modules, data model, and dependencies before planning anything.

Incremental Migration Planning

Where possible, moving functionality across in stages rather than a single high-risk cutover.

Technical Debt Reduction

Using the move to ASP.NET Zero's structure as an opportunity to clean up what the legacy system has accumulated, where that's in scope.

Data Migration

Moving existing data from Entity Framework 6 to EF Core as part of the planned stages, not as an afterthought.

Why Us

Why ETECHTICS for ASP.NET Zero Migration

Legacy Assessment Experience

Reviewing what a system actually does before planning how it moves, rather than assuming.

Incremental by Default

Migrations are planned in stages where possible, to reduce risk to a system still in use.

Framework Depth Since 2019

The destination architecture, ASP.NET Zero with the latest Angular, is one we've specialized in for years.

Support After Go-Live

Migration doesn't end at cutover. See Support & Maintenance for what comes after.

FAQ

ASP.NET Zero Migration & Modernization FAQ

What counts as ASP.NET Zero migration and modernization?

Moving a legacy application, or one built on a different platform, onto ASP.NET Zero's architecture, as distinct from upgrading an ASP.NET Zero application that's already on the framework to a newer version.

Can you move an AngularJS ASP.NET Zero application to the latest Angular?

Yes. This is the most common migration we handle. The AngularJS 1.x front-end is rebuilt in the latest Angular, and the ASP.NET MVC 5 back-end is moved to ASP.NET Core, so the application matches the stack ASP.NET Zero uses today.

Why move away from AngularJS now?

AngularJS reached the end of its long-term support in December 2021, so it no longer receives security fixes or compatibility updates. Staying on it makes new features, hiring and security reviews harder over time.

What usually prompts a migration?

An outdated framework or platform, accumulating technical debt, dependencies that are no longer maintained, or new business requirements the current codebase can't accommodate cleanly.

Does migration happen all at once or incrementally?

It depends on the application. Where possible, functionality and data are moved across incrementally rather than in one cutover, to reduce risk and keep the existing system usable during the transition.

What is assessed before a migration starts?

The existing application and its data model, so the migration plan is based on what the system actually does today rather than assumptions about it.

What's the difference between migration and framework upgradation?

Framework Upgrade is for an application already on ASP.NET Zero moving to a newer version. Migration & Modernization is for moving a legacy system, or one on a different platform, onto ASP.NET Zero for the first time.
