VMWare License

 I have three VMWare hosts. Two hosts with ESXi v5.5 and one host with ESXi v6. When I was setting up two ESXi v5.5 hosts, I purchased vSphere 5 Essentials (which is supposed to be good for three hosts).
 I have vCenter Server that manages two ESXi v5.5 hosts, but I can't add the new ESXi v6 host to my vCenter because of the version difference.
 I would like to upgrade all my ESXi v5.5 hosts to v6.
 That said, I like to know my options:
 (1) Buy new vSphere V6 Essentials Bundle Kit - 3 Host Max - 2 CPU Per Host (Part#: VS6-ESSL-KIT-C)
 (2) Ask a VMware sale person to see if I can purchase an v6 upgrade from current vSphere 5 Essentials .
 (3) Somehow I can manage all three hosts with current vSphere 5 Essentials  license

This is correct, the vSphere 5 Essentials license is for 5.5 ONLY.

Have you upgraded your vCenter Server from 5.5 to 6.0 yet ?

Remember that vCenter Server 6.0 and ESXi 6.0, give you 60 days FULL EVALUATION mode, so you do not need licenses for th first 60 days.

If you have Support and Subscription which is current, you can go to the MyVMware Portal and Upgrade your 5.5 licenses to 6.0, and then apply the licenses within 60 days, or at the end of the 60 days.

1. Yes certainly you could purchase another set of licenses and add more money to the VMware pot! but why! (depends if you have current sub!).

2. You can, see the portal, if you have valid subscription.

3. No you cannot do this. and you will need to upgrade to vCenter 6.0 anyway

VMWare upgraded my vSphere Essential 5 to vSphere Essential 6 when I paid for the upgrade fee of $100. It was much cheaper than buying a whole new vSphere Essential 6 ($600).
Thank you.

vCenter 6"Have you upgraded your vCenter Server from 5.5 to 6.0 yet ?" --> Yes I un-installed vCenter 5.5 from one server and installed vCenter 6 on another server and added three hosts that are running ESXi v6.

Thanks for your help!

  Why does it generate license expiration warning when there is vCenter 6 license entered?
