Cevap
The essential pre-implementation change management activities are testing the upgrade in a non-production staging environment and creating a documented backout plan to restore functionality if issues arise.
Formal change management procedures require pre-implementation testing in a non-production environment to evaluate security impacts and potential conflicts. Additionally, establishing a documented backout plan is mandatory to ensure that the environment can be safely restored if errors or vulnerabilities manifest during execution.
