Our current traditional model looks like this:
-3 node cluster
-FC storage array
-ESXi version 5.5
Our new Nutanix model looks like this:
-3 node Nutanix cluster
-NFS local storage
-ESXi version 6.0 update1a
-vCenter 6.0 update1a
-4Gbps network (NIC teamed 4x1Gbps)
I'd like an option that requires little to no VM down time if possible. We currently have 2 vCenter servers (1 for the old cluster and 1 for the Nutanix cluster).
Can I create an NFS export so I can access the Nutanix storage from my old ESXi hosts? Can I add HBAs in my Nutanix hosts so I can connect to my shared storage FC fabric? Is VMware's standalone converter an option? Will I need to move the old hosts to the new vCenter to be able to live migrate the VMs from the old cluster to the new? Which option requires the least amount of VM downtime?
Any help or guidance is greatly appreciated.

RE VSS / VDS, etc - yes, you need to have VSS on at least one target HOST, nothing to do with vCenter
Basically you can just DROP one physical uplink on ONE nutanix node, configure VSS for that node (you dont have to do LACP, just do one link, no physical switch changes), and use that is your "gateway" into the new environment.
