A vSphere administrator wants to upgrade NFS3 datastores to NFS4.1 on ESXi 6.5 hosts with running production virtual machines.
Which option is valid?
A. Run ESXi command to upgrade the datastore.
B. Unmount the datastore from a single host, then mount it as NFS 4.1 datastore, and repeat this one host at a time until the mount has been upgraded on all hosts.
C. Create a new NFS 4.1 datastore, and then use Storage vMotion to migrate virtual machines from the old datastore to the new one.
D. Right click the datastore and upgrade it as a NFS 4.1 datastore.
If you want to upgrade your NFS 3 datastore, the following options are available:
Create the NFS 4.1 datastore, and then use Storage vMotion to migrate virtual machines from the old datastore to the new one.
Use conversion methods provided by your NFS storage server. For more information, contact your storage vendor.
Unmount the NFS 3 datastore, and then mount as NFS 4.1 datastore.
