What Is Application Replatforming?

Application Replatforming, sometimes called "lift, tinker, and shift", moves an application to a new platform while making limited, targeted changes, such as swapping a self-managed database for a managed cloud service, without a full rearchitecture.

Replatforming sits in the middle ground between doing nothing and a full rebuild, capturing some of the operational benefits of the cloud (lower maintenance overhead, managed scaling, better resilience) without the cost and risk of redesigning the application. For enterprises with a large portfolio of applications, it's often the strategy that delivers the best return relative to effort, which is why some industry analysis flags it as the most under-used of the standard modernization approaches.

We use replatforming when an application would benefit meaningfully from cloud-managed services, such as a managed database or container platform, but doesn't need, or can't justify the cost of, a full architectural redesign. Typical changes include moving a self-hosted database to a managed service, or adopting managed container orchestration without restructuring the application itself. This gives clients a genuine reduction in operational burden and improved reliability, at a fraction of the cost and timeline of rearchitecting or rebuilding, which makes it a strong default choice across a broad slice of a typical application portfolio.
