5. Upgrading hosts with Update Manager and vCenter Server 5.5
6. Upgrading virtual machines

Some time ago I wrote a series of posts on upgrading to vSphere 5.1. This time I’d like to have a look on upgrade process to version 5.5. I’d like to cover vCenter Server upgrade, hosts upgrade as well as virtual machines hardware and VMtools upgrade. So, with vSphere 5.5 installation media in hand, let’s go.

ATTENTION FOR UPGRADES FROM 4.X

First, make sure you have a look on system requirements for vCenter Server 5.x – if you’re upgrading from 5.0 or 5.1, they will be the same. Since you can upgrade vCenter Server directly from version 4.x, if that’s your case you may want to have a look on system requirements as they will differ. Secondly, when upgrading from 4.x a new component called Single Sign-On will be installed – if you have no experience with SSO I strongly recommend reading first VMware KB Methods of upgrading to vCenter Server 5.5, part called „What is vCenter Single Sign-On and how it affects vCenter Server upgrades”, my post on SSO when upgrading to 5.1 as well as other VMware resources on SSO. You may also want to read VMware KB: Upgrading to vCenter Server 5.5 best practices.
