Question about NFS datastores

Hi everyone, I am a fairly experienced VMware admin however almost all my experience with shared storage is using fibre channel. I am upgrading one of our small, somewhat remote sites which is presently using NFS shares for the datastores. There is a new SAN being ordered, but I’d like to get a jumpstart on the upgrades by using the existing storage for now. So right now we have 5 ESXi 5.5 hosts in a cluster along with a vCenter 5.5 server. I am planning to deploy the new physical hosts in parallel, put them in a new cluster of their own, and deploy a brand new VCSA.

My question is, can I mount the existing datastores from the new hosts without affecting the old hosts? Since they will be technically mounted to 2 different clusters, will there be any adverse effects? The only info I could find related to sharing NFS datastores among hosts is within the same cluster.

Has anyone here done anything similar? I would prefer to use fibre channel but that is not an option at this time.

EDIT: I should clarify, I realize a datastore is a formatted disk object specific to VMware and so trying to mount an NFS volume from another VMware environment seems like it would not work. Is there any way to do this so that the datastores are preserved?

  1. You can mount the new nfs datastore(s) on your existing hosts, storage vMotion the VMs over to the new NFS stores, remove the 5.5 hosts from your 5.5 vCenter, add them into your new VCSA (as long as it’s only 6.5) and then vMotion your VMs to the new hosts. Both environments can use the same NFS stores during the migration.
