What is Application Migration

Want to optimize your IT infrastructure without rebuilding everything from scratch? Learn about Application Migration.

A well-optimized IT environment improves operational efficiency and helps businesses adapt to changing demands. However, transferring applications to a new platform or environment can seem daunting, especially if you’re unfamiliar with the process or the tools involved.

Migrating applications manually requires significant effort and time, as it involves evaluating systems, adapting code, and ensuring minimal downtime.

This is where understanding different types of application migration can simplify the process and save time.

In this guide, we’ll explore the key types of application migration, their benefits, and how to implement them effectively.

Types of Application Migration

  1. Lift and Shift Migration
    Also known as rehosting, this involves moving an application to a new environment without altering its architecture or code. This is a quick solution often used when transitioning from on-premises infrastructure to the cloud.
  2. Replatforming
    In this approach, minor modifications are made to the application to leverage the benefits of the new environment, such as using managed services in the cloud. It’s more efficient than lift and shift but doesn’t require a complete overhaul.
  3. Refactoring
    This involves significant changes to the application’s architecture and code to optimize it for the target platform. It allows leveraging advanced features of the cloud, improving performance, scalability, and maintainability.
  4. Rehosting
