PMP Practice: Communicate Change Status

Nikhil Kulkarni-Patel is managing a data center consolidation project for Elaborate Simplicity Group. The project is using a predictive approach with a detailed integrated baseline and formal change control board approvals. Three months into execution, the procurement department notifies Nikhil that a critical networking hardware vendor has announced end-of-life for a component specified in the technical design. The approved change request requires substituting equipment from a different vendor, resulting in modifications to installation procedures, training materials, and operational support documentation. The change control board has already approved the change, budget has been reallocated, and the new equipment is on order. However, the project management plan, technical specifications document, and stakeholder communications all still reference the original equipment. Multiple team members are working from outdated documents. Which approach would be MOST effective for Nikhil to manage this situation?
