Moving VM swap file location to another Datastore

Hi All,

Was in a task to move the 1000's of VM's swap file location to another datastore which is newly assigned to us from the existing swap file datastore which is going to be decomissioned.

Eager to check if any one did moving VM's swap file location from one datastore to another, and what all the steps taken to move.

Does it require VM downtime?

Thanks a ton in advance.
