What is Application Modernization?

Application modernization involves updating and transforming older applications to take advantage of modern technologies and architectures, making sure they stay useful, efficient, and adaptable in today’s fast-moving digital world. This process covers various actions like moving to new hosting environments, adjusting platforms, restructuring code, redesigning architectures, rebuilding from scratch, or even completely replacing the applications.

Application Modernization Process

To modernize an application is a journey that involves various stages for transforming the old systems into applications which are efficient, modern and can scale. It is not just about technological updates but enhancing the whole business operations and improving user experience. Let us have an in-depth look at the process of application modernization:

1. Assessment

The first step in application modernization involves:
  • Inventory and Analysis: Cataloging existing applications and understanding their functions, dependencies, and performance.
  • Business Alignment: Evaluating how each application supports business goals and identifying key drivers of business value.
  • Technology Evaluation: Analyzing the current technology stack to identify outdated or unsupported technologies.

2. Planning

Following the assessment, the next step is to develop a detailed modernization roadmap, which includes:

  • Modernization Strategies: Choosing the best approach (like rehosting, replatforming, refactoring, rearchitecting, rebuilding, or replacing) for each application based on its unique requirements.
  • Prioritization: Ranking applications by business importance, complexity, and potential benefits, to determine the order of modernization.
  • Resource Allocation: Identifying necessary resources such as budget, skilled personnel, and tools.
  • Risk Management: Anticipating and mitigating potential risks to minimize disruption during the modernization process.

3. Execution

During execution, modernization strategies are implemented, Here are the 6 R’s of modernization:

  • Rehosting: Known as “lift and shift,” moves applications to modern infrastructure with minimal changes, ideal for enhancing reliability and scalability.
  • Replatforming: Adjusts applications for modern platforms like cloud environments, improving flexibility and efficiency.
  • Refactoring: Restructures code to boost performance, scalability, and maintainability without altering external functionality.
  • Rearchitecting: Redesigns architecture to leverage technologies such as microservices and serverless computing for enhanced agility and scalability.
  • Rebuilding: Rewrites applications using current technologies and best practices to meet present business needs.
  • Replacing: Swaps out legacy applications for commercial software or SaaS solutions better suited to business requirements, enhancing functionality and reducing maintenance.

4. Testing

Once the modernization changes are implemented, thorough testing ensures the updated applications meet required standards. This includes:
  • Functional Testing: Checking that the application operates correctly and fulfills all specified requirements.
  • Performance Testing: Assessing how well the application performs under anticipated workload conditions.
  • Security Testing: Identifying and addressing any security vulnerabilities introduced during modernization.
  • Compatibility Testing: Ensuring the modernized application works seamlessly with existing systems and integrations.

5. Deployment

Once testing is successfully completed, the modernized applications are deployed to the production environment. This phase involves:

  • Deployment Planning: Developing a detailed deployment plan that includes timelines, resource allocations, and rollback procedures in case of issues.
  • User Training: Providing training to end-users and IT staff on the new features and functionalities of the modernized applications.
  • Data Migration: Ensuring that all necessary data is accurately migrated from the legacy system to the modernized application.
  • Go-Live Support: Offering support during the initial go-live phase to quickly address any issues that may arise.

6. Monitoring and Optimization

Post-deployment, continuous monitoring and optimization are crucial to ensure the modernized applications deliver optimal performance and business value. This includes:

  • Performance Monitoring: Using monitoring tools to track application performance and identify any areas for improvement.
  • User Feedback: Collecting feedback from end-users to understand their experience and identify any additional enhancement opportunities.
  • Continuous Improvement: Regularly updating the applications to incorporate new features, fix bugs, and improve performance based on user feedback and technological advancements.
  • Scalability Planning: Ensuring the application can scale efficiently to handle increasing loads and support business growth.

Key Considerations in the Application Modernization Process

Critical factors to consider in the enterprise application modernization process are – 

Integration with Cloud:

Cloud-based services provide enhanced scalability, flexibility, and cost efficiency for modern applications. This may involve moving applications onto cloud platforms and embracing cloud-native architectures.


Throughout the process of modernization, strong security measures ensure that sensitive data is protected and regulatory standards are followed.

Cost Management:

Compared to the anticipated benefits, the cost associated with upgrading must be balanced out so that a credible return on investment can be attained.

Stakeholder Engagement:

For support during modernization initiatives, it is very important to involve critical stakeholders in order to attain alignment with business objectives.

Enterprise can reinvent their legacy systems into contemporary effective scalable apps by following a methodical app modernization approach.
