To change the subscription options for a datacenter migration scenario, the administrator can use the Change Plan option in the Scenario Builder. This option allows the administrator to modify the plan type, duration, and discount for the selected cloud provider without running a new scenario. The Change Plan option also updates the cost and savings estimates based on the new subscription options. The other options are not relevant for changing the subscription options. Change Cloud Provider is used to switch to a different cloud provider for the scenario. Edit Configuration is used to modify the configuration settings, such as CPU, memory, and storage, for the scenario. Edit Discount is used to apply a custom discount percentage for the scenario. References: Change Plan, Scenario Builder, Create a Scenario for Data Center Migration
