I am trying to rebuild a vmware environment (that was poorly built!) and as part of that i am looking at upgrading/replacing the software to the latest, but i am unsure what i need to buy as i find it a little complex.
The current build I am wiping and rebuilding has;
vSphere 5 Essentials Plus and ESXi 5.5
vCenter Server 5 Essentials
I have 8 CPUs (2 per host)
There are (now) four hosts and two SANS, so what I can see I would need;
4 x ESXi 6.0
1 x vSphere Standard (6.0)
1 x vCentre 6.0
Can i just upgrade from my current vSphere 5 to version 6? Or do i need to buy new licenses etc?
