Which of the following processes 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 forklift migration. This approach allows organizations to move applications from their existing environment to a new environment (such as a cloud platform) while making few or no modifications to the application's code. Forklifting is particularly beneficial for scenarios where the application is tightly coupled with its existing infrastructure, and significant changes to the codebase may not be feasible due to time, cost, or operational constraints.

By utilizing forklift migration, businesses can achieve a quicker transition to the cloud without disrupting their existing applications. This method can be particularly effective for legacy applications that require minimal handling yet need to be modernized in their deployment setup.

While other processes listed have their specific purposes, they do not pertain directly to the migration of applications with minimal code changes. For instance, sandboxing is related to creating isolated environments for testing or development; data masking is about protecting sensitive information; and tokenization refers to replacing sensitive data with unique identifiers. Each of these processes serves different functions that are not focused on the migration aspect as forklift migration does.
