The term "cutover" refers to a process in which an organization or system transitions from using one technology, method, or approach to another. This can involve changing software systems, hardware infrastructure, communication networks, or other components that are critical to the functioning of the organization. The cutover period is when both the old and new technologies or methods are being used simultaneously in order to ensure a smooth transition without any disruption of service. During this time, there may be increased monitoring and testing to identify and address any issues that arise. Once everything has been thoroughly tested and verified, the final switch can be made, and the old system is completely phased out. The term "cutover" refers specifically to the point in time when this transition occurs.
