Comprehensive and Detailed In-Depth Explanation:

The scenario outlines the process of decommissioning a legacy application after a new product has successfully taken over its functions. This corresponds to the End of Life phase in the Software Development Life Cycle (SDLC).

The End of Life phase involves retiring outdated systems and transitioning users to newer solutions. This phase ensures that obsolete applications are systematically phased out, reducing maintenance costs and potential security vulnerabilities associated with unsupported software.

In this case, running both the legacy and new applications concurrently provided a safety net to ensure the new system's stability. After confirming the new product's reliability, the organization proceeds to disable the legacy system, marking its End of Life.

White box testing, also known as clear box testing, glass box testing, transparent box testing, and structural testing, is a method of software testing where the internal structure, design, and coding of the software are tested to verify the flow of input-output and to improve the design, usability, and security. It involves looking at the structures that are internal to the system, with the tester having knowledge of the internal workings of the product. This type of testing is concerned with examining the internal logical structures of the program and is typically performed by stepping through the code line by line to analyze the program for potential errors, which aligns with the description of the control test in question.
