CompTIA CASP+ Practice Test

When replacing a legacy security product, what is the best sequence of activities to follow?

1. Test new solution, migrate, decommission

2. Migrate, decommission, test

3. Decommission, test, migrate

4. Test, decommission, migrate

The correct answer is: Test new solution, migrate, decommission

The best sequence of activities to follow when replacing a legacy security product is to first test the new solution, then migrate, and finally decommission the old system. Starting with testing the new solution allows you to ensure that it meets all necessary security requirements and functions properly within your environment. This step is critical to identify any issues or inadequacies before fully committing to the switch. If the new solution does not perform as expected, adjustments can be made, or even another product can be considered, which significantly reduces risks associated with deployment. Once testing confirms that the new solution is effective, you can migrate to it. This migration involves moving data, configurations, and operations to the new security product. It’s crucial to conduct this step only after thorough testing to avoid interrupting security services or exposing the organization to potential vulnerabilities. Finally, decommissioning the legacy product should take place after the migration is completed successfully and all functionalities are confirmed operational. This ensures that there is no overlap or confusion between the two systems, and it allows for proper removal of the old system without compromising security during the transition. This carefully considered sequence minimizes disruption, maintains security integrity, and ensures a smoother transition to the new security solution.
