If an administrator is upgrading to vSphere 7.0, which statement is true regarding the upgrade from NFS v3 to NFS v4.1?

When upgrading to vSphere 7.0, the statement about unmounting and remounting NFS v3 datastores using NFS v4.1 is indeed accurate. This reflects the flexibility offered by vSphere 7.0 in managing NFS datastores during the upgrade process.

NFS v3 and NFS v4.1 are different protocols, with v4.1 providing enhancements such as improved performance, security features, and better handling of concurrent operations. Admins can successfully unmount existing NFS v3 datastores and then mount them again using the NFS v4.1 protocol after the upgrade, allowing for a smoother transition to the newer protocol without losing access to the data stored in those datastores.

Creating a new VMKernel port for NFS v4.1 is not necessarily a pre-requisite for the upgrade, making the second statement less relevant. Meanwhile, the automatic conversion of NFS v3 datastores to NFS v4.1 post-boot does not occur, as the process requires manual intervention to unmount and remount. Lastly, it's important to note that ESXi 7.0 indeed supports NFS v4.1, countering
