Top 7 Legacy Application Modernization Approaches of AngularJS Web Development Company

There are several methods for modernizing old systems that are tailored to specific requirements and have distinctive features. Here are seven common approaches to legacy application modernization, along with examples:

Top 7 Legacy Application Modernization Approaches of AngulaJS Web Development Company

1. Rebuild

Rebuilding involves rewriting the application from scratch while retaining its existing functionality. It means throwing out the existing codebase and starting with the most recent options. This approach allows for leveraging modern technologies, frameworks, and design patterns.
For example, rebuilding a legacy application using a modern web development framework like AngularJS, resulting in improved user experience and performance.

2. Rehost

This approach involves migrating the application to a new platform while maintaining its core functionality. For example, moving an application from an on-premises server to a cloud infrastructure such as Amazon Web Service.Rehosting offers benefits like improved scalability, reliability, and reduced infrastructure costs.

3. Refactor

Refactoring is the process of enhancing an existing codebase without altering its core functionality. Examples include restructuring the database or rewriting a portion of the system. This strategy seeks to improve the underlying design and optimize particular parts without altering the general behavior of the program.

Refactoring is typically employed in hybrid situations where legacy system components have code that has been optimized for performance. Refactoring typically involves updating the backend components while leaving the frontend or functionality unaffected.

4. Replatform

Replatforming is the process of transferring a legacy system to a new platform or technology stack, frequently after some adjustments to assure compatibility. It tries to maximize the advantages of the new platform while reducing the necessity of significant code changes.

Little adjustments, however, result in limited advantages. Only the parts that are operating on a new system will be adaptable, while the rest won’t be able to keep up with the demands of the contemporary market.

5. Retain

The Retain/Encapsulate strategy for modernizing historical systems entails retaining the current application while enclosing it in a more up-to-date shell. By separating the old system from the rest of the architecture, it will be possible for it to continue operating without impeding the adoption of new technologies or operational procedures.

For a growing business, keeping a legacy system in place is more challenging than updating it. Organizations need a long-term plan in this regard to guarantee the efficient operation of all app components.

6. Replacing

Replacing involves replacing the legacy application entirely with a new, off-the-shelf software package or a custom-built solution. For instance, replacing an outdated accounting system with a modern enterprise resource planning (ERP) system like SAP or Oracle. This approach can provide access to advanced features, improved integration capabilities, and vendor support.

7. Rearchitect

This method involves changing the design of the application code to address performance and scalability difficulties. Advanced technical knowledge is necessary because it is a rather complicated process.

Rearchitecting has various advantages, including enhancing app usability and making it easier to add new features in the future. This strategy is risky, though, as it has the potential to alter how a corporation operates and how the system functions in general.
