Best Upgrade Method Free ESXi 3.5 to Paid/Enterprise 4.1
Posted on 2010-09-17
We're running the free version of ESXi 3.5 I wanted to find out the best way to move to the enterprise level VMware 4.1. I understand there really isn't an upgrade path available so I need to determine the best method for accomplishing this goal.
(2) Physical Hosts - Each host has approximately 4 virtual machines.
Datastore resides on local storage RAID 5 array.
We just purchased a 4TB ready NAS which will be available for use as a datastore as well (FYI).
I want to upgrade the (2) aforementioned hosts from 3.5 to 4.1. I'd like to continue using my VMs on the existing local storage (because our local storage is quite big, but if I need to migrate servers to the NAS temporarily I can do that as well.
Please provide a step by step. Thank you in advance!
