Decommissioned

"Decommissioned" refers to the process of taking a facility, piece of equipment, or system out of active use, typically because it is outdated, no longer needed, or being replaced. This involves disconnecting or removing operational components, ensuring safety, and sometimes repurposing or dismantling the entity. For example, a power plant that stops generating electricity and is shut down for good is decommissioned. The term can also apply to military equipment, ships, or technology that has been retired from service. Overall, decommissioning is a formal process to safely cease operations of something that was once in active use.
