Mikasa's organization has been using a cloud service for the past five years which will soon become unavailable. In this situation, which phase of the vendor relationship should Mikasa prepare for regarding this service?

End of Life (EOL) refers to the state when a system or service is no longer available, supported, or functioning. Mikasa must prepare to transition away from the service smoothly, either by replacing it with another service or discontinuing its use. Memorandum of Understanding (MOU) and Non-Disclosure Agreement (NDA) are not directly relevant in this context. Similarly, a Last Will and Testament is not utilized for managing a service's EOL.
