I have an old ESXi 4.1 host connected to a Drobo SAN using iSCSI. It's hosting two servers totaling about 700GB. Would it be easier to take one of my existing ESXi 6 hosts and connect it to the Drobo SAN (so ti sees the new SAN and the old Drobo SAN), drop the guest server from ESXi 4's inventory and add it to the ESXi 6 host then migrate (move)? Any other alternatives or suggestions? I have done this way prior but just wondering if there is a quicker way.
