" Coordinate change and cutover execution: prepare change-advisory submissions, change windows, methods of procedure, validation testing, and rollback plans; track decommission requests (RITMs) through power-off and physical removal; coordinate across network, storage, security, SRE, and vendor teams, including physical and network decommission hand-offs between sites.
