What is the advantage of a parallel conversion?

The advantage of a parallel conversion is that it allows for simultaneous operation of both the old and new systems, which minimizes the risk of disruption during the transition. This approach enables users to verify that the new system functions correctly while still relying on the familiar old system. Additionally, it provides a safety net, as any issues with the new system can be addressed without affecting ongoing operations. However, it may require more resources and can lead to higher operational costs during the transition period.
