Which conversion method involves using the old system until the new system is confirmed to be working well?

The method that involves using the old system alongside the new system until the new one has been confirmed to be functioning effectively is known as parallel conversion. This approach allows an organization to maintain the reliability and consistency of their operations by keeping the old system in place while the new system is being tested and integrated.

In parallel conversion, both systems run simultaneously, which enables the staff to compare outputs from the old and new systems. This comparison is essential for validating the accuracy and performance of the new system before fully transitioning to it. Furthermore, should any issues arise with the new system, employees can continue working with the old system without interruption, ensuring continuous operational stability.

This approach is particularly beneficial in environments where data integrity and reliability are crucial, as it minimizes the risks associated with transitioning to a new system. Instead of abruptly switching from the old to the new, parallel conversion provides a safety net, making it easier to address any unforeseen issues during the initial implementation phase.
