Virtual Platform Update - Vmware

Goodnight,

Currently in the company where I am working, we have to update all our virtual infrastructure. Up to now we have the following:

-Vmware ESXi 5.5
-Vcenter Server 5.5 u2
-Site Recovery Manager 5.8

Everything we want to bring to version 6.0.

Regarding the update what would be the order that should be executed first.

I would start first with the ESXi, then the Vcenter, and finish with the SRM.

We have four environments, Production, quality, development and contingency.

All our physical equipment is HP.

Stay tuned to your comments.

Best regards.

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

I would recommend to go with vCenter , SRM and then ESXI.

if you upgrade host fist it will get disconnected from the vCenter server.

This is known as SSL3 has been removed.

if you upgrade ESXi first, you will find your current version of vCenter will not be compatible with them!

vCenter Server must always be a higher version than ESXi.

Do you have licenses and have you checked all your hardware is on the HCL for the upgrade.

What specific builds of ESXi, vCenter Server and SRM do you have, because you will need to check the matrix, to check compatibility.

But ESXi must not be upgraded first.

Good Morning,

In order to carry out these updates I must have valid licenses?

Then the order that should follow is to update:

Vcenter
SRM
ESXi

Which version of Vcenter should you update to be compatible with ESXi 6.0. or should I upgrade to ESXi 6.1?

Stay tuned to your comments.

Good afternoon,

In mind Andrew,

Currently for updates should I have new licenses? or with the licenses that I currently have? It's the first time I'm going to update the infrastructure, which is why I have some doubts.

Best regards.

You will need new licenses for 6.x, applying after you update.

After updating to 6.0, you will run in evaluation mode for 60 days.

In mind Andrew,

Would these new licenses apply to ESXi, Vcenter Server and SRM?

We currently have 20 servers with the ESXi installed, require 20 licenses for each of the host?

Additional we have 5 Windows servers each with a Vcenter Server and Four Windows servers with the SRM. Do I require new licenses for each server?

If you are moving to 6.0 of ESXi and vCenter Server - you will require new licenses for ALL servers.

ESXi is licensed per CPU socket filled, and vCenter Server is a single license.

If you have Support and Subscription, and it's still valid and in support, you will be able to upgrade for free, and all the licenses will be in your MyVMware panel.
