Application Migration

Application migration is the process of transferring an application program from one environment to another. An example is migration from a company’s local server to a cloud provider’s environment or from one cloud environment to another.

The purpose of migration may be to increase productivity, reduce costs, flexible scalability, or take advantage of new technologies and platforms.

Application Migration Strategies

Rehosting (lift-and-shift) — transferring applications without any changes.

Refactoring is the redesign of an application, often in order to take advantage of cloud features.

Revision — modification or expansion of the code base of an existing application before migrating it.

Perestroika is the reworking of an application from scratch using cloud native technologies.

Replacement — abandoning an existing application and switching to another one.

The choice of strategy depends on the complexity of the application, business requirements and budget constraints.

The importance of application migration

Improving efficiency. Migration to modern platforms can improve application performance and reduce maintenance requirements.

Cost reduction. Cloud platforms offer a pay-as-you-go model, which can lead to significant cost savings compared to on-premises infrastructure maintenance.

Increased scalability. Cloud platforms allow applications to scale on demand and quickly adjust to changing loads.
