A systems administrator plans to upgrade a server to the latest operating system. Which of the following should the administrator do before placing a change request?

Establishing a scope involves defining the boundaries, objectives, affected systems, risks, and resource requirements of the server OS upgrade. This crucial preliminary step ensures that the change is well-defined and understood, providing the necessary details for creating a comprehensive change request that can then be submitted for formal approval.

Getting change board approval is a subsequent step that occurs after a detailed change request, based on an established scope, has been submitted.

Creating a test environment is part of the implementation and validation phases, typically executed after the change has been planned and approved, not before the initial request.

Rolling back previous changes is a contingency measure or part of a remediation plan, not an initial step to take before proposing a new major system upgrade.
