$

Hi All ...
In the sixteenth part of our series, we'll discuss vSphere Upgrading. We'll cover vSphere Upgrading from 3.x/4.x to 5.x as well as in-place upgrade of vCenter Server Appliance.

Short, but important.

Now, Let's Start...



1. Upgrading ESXi 5.1 Options:

Force Migrate ESXi, Preserve VMFS Datastore:

This will take your current installation and configuration and attempt an upgrade/migration and keep your VMFS Datastores intact, so your VMs will be preserved if things go wrong.

Install ESXi, Preserve VMFS Datastore:

This will install a fresh copy of ESXi 5.1 and leave your VMFS datastores intact, this will erase all custom configurations, it's a clean slate basically and you will have to re-add your VMs back to your inventory once you have reconfigured your host server.

Install ESXi, Overwrite VMFS Datastore:

This does exactly what it sounds, it will install a clean copy of ESXi 5.1 and overwrite your current datastores - you will lose all information on that datastore.

 

 

2. Steps:

1- ) Upgrade vCenter to 5.1 after installing SSO & Inventory Service.

2- ) Upgrade vSphere Client & Web Client.

3- ) Upgrade Update Manager if exists.

4- ) Upgrade ESXi Hosts.

5- ) Upgrade VMware Tools.

6- ) Upgrade VMware HW Version (VMs, DVSs, ect.)

7- ) Upgrade Datastores VMFS.

In case of upgrading failure, you have to install each component (SSO, then Inventory Services and finally vCenter Server 5.1) individually.

 

 

3. In-Place Upgrade of vCenter Appliance:

This official step-by-step guide by VMware is for upgrading vCenter Server Appliance:
