Which conversion method involves implementing a new system while still using the old one?

The parallel conversion method involves running both the old system and the new system simultaneously. This approach allows for a direct comparison of the two systems, providing a safeguard against potential issues with the new implementation. By using the old system concurrently, organizations can ensure that they still have access to familiar processes and can mitigate risks associated with the new system. If discrepancies or problems arise during the implementation of the new system, the organization can rely on the old system while solutions are identified and implemented.

This method is particularly useful for critical systems where continuity of operations is essential. Organizations can gradually transition to the new system without the fear of downtime or loss of data, enhancing confidence in the migration process. The parallel method provides the opportunity for thorough testing and training while minimizing disruption to business activities.
