3. Choose the Right Modernization Approach

Rehosting (Lift and Shift)

• Pros: Quick and less expensive, minimal code changes required.
• Cons: Does not fully leverage cloud capabilities or modern architecture.

Replatforming

• Pros: Balances cost and benefits by making minimal code changes while leveraging new platforms.
• Cons: May require some adjustments to the application.

Refactoring

• Pros: Fully optimizes the application by rewriting code to improve performance and scalability.
• Cons: Time-consuming and expensive, requires significant effort.

Rebuilding

• Pros: Allows for complete customization and modernization.
• Cons: The most time-consuming and costly approach, but offers the best results.

Replacing

• Pros: Implements an entirely new system with modern features and capabilities.
• Cons: Can be disruptive to current operations and requires extensive training.

4. Plan for Data Migration

Data Assessment

• Data Inventory: List all the data that needs to be migrated.
• Data Quality: Ensure the data is clean and accurate before migration.

Data Migration Strategy

• Select Tools: Choose the right tools for data migration based on the volume and type of data.
• Plan Migration: Develop a detailed plan for data migration, including timelines and responsibilities.

5. Implement Modernization

Develop and Test

• Development: Start the development process based on the chosen modernization approach.
• Testing: Conduct thorough testing to ensure the new system works as intended and meets all requirements.

Deploy

• Deployment Plan: Create a deployment plan to transition from the old system to the new one smoothly.
• Monitoring: Continuously monitor the new system post-deployment to identify and resolve any issues quickly.

6. Train Your Team

Training Programs

• User Training: Provide comprehensive training for all users to ensure they can effectively use the new system.
• Technical Training: Offer in-depth training for IT staff on maintaining and supporting the modernized application.

Support

• Ongoing Support: Set up a support system to assist users with any issues or questions they may have.
• Documentation: Create detailed documentation for the new system to aid in troubleshooting and future updates.
