Which feature can be used to evacuate a storage array that has been replaced?

Storage vMotion is the correct choice for evacuating a storage array that has been replaced. This feature allows virtual machine files to be moved from one datastore to another while the virtual machines remain powered on, ensuring minimal downtime and continued operations. When a storage array is replaced, data needs to be migrated away from the old datastore to the new one, and Storage vMotion can handle this seamlessly, allowing for dynamic reallocation of storage resources without interrupting the virtual machines' availability.

The other options do not serve the purpose of evacuating storage arrays. vSphere vMotion is specifically designed for migrating running virtual machines from one ESXi host to another without downtime but does not address the need to move data across storage arrays. Proactive HA is related to high availability and monitors hardware health to take action on VMs if an issue is detected, whereas Predictive DRS focuses on resource allocation and load balancing among hosts but does not cater to the migration or evacuation of data from a storage array.
