Which process involves migration of an application with minimal code changes?

The process that involves the migration of an application with minimal code changes is known as "forklifting." This approach allows for the transferring of applications from an on-premises environment to the cloud with little to no modification to the existing code.

The key aspect of forklifting is that it preserves the application’s existing architecture and functionality while moving it to a new environment. This is particularly advantageous for organizations looking to take advantage of cloud benefits, such as scalability and reduced infrastructure costs, without the need to rewrite or extensively modify their applications.

In contrast, other concepts such as sandboxing, data masking, and tokenization do not focus on application migration. Sandboxing typically refers to a testing environment where changes can be trialed safely. Data masking involves obscuring specific data within a database, primarily for security or compliance reasons, and tokenization replaces sensitive data with non-sensitive equivalents for secure processing. While important in their own right, these processes do not facilitate the migration of applications in the way that forklifting does.
