Upgrading ESX/ESXi Hosts and Virtual
Machines 6
Upgrading ESX/ESXi hosts and virtual machines to vSphere 5.0 is the most time-consuming aspect of this
middle phase of a VMware View upgrade.
Upgrading from ESX/ESXi 3.5 involves more steps than upgrading from ESX/ESXi 4.x.

Upgrade ESX 3.5 Hosts and Their Virtual Machines
Upgrading ESX 3.5 hosts and virtual machines involves upgrading the host, the virtual machine virtual
hardware version, and the version of VMware Tools on the virtual machines.
This procedure provides an overview of the tasks you must perform during the second and subsequent
maintenance windows. To complete some of these tasks, you might need step-by-step instructions found in
the vSphere Upgrade Guide and the VMware View Administrator's Guide.
Prerequisites
n
Complete the procedure described in “Upgrade View Connection Servers in a Replicated Group,” on
page 25.
n
Perform the ESX/ESXi upgrade preparation tasks listed in the vSphere Upgrade Guide.
n
Verify that you have the correct license key for vSphere if you are upgrading Virtual Infrastructure
components to vSphere.
n
Verify that all ESX/ESXi hosts are members of a cluster. If you want to upgrade a standalone host, place
it in a single-host cluster.
Procedure
1 Upgrade ESX/ESXi hosts to vSphere 5.0, cluster by cluster.
For instructions, see the vSphere Upgrade Guide. If you have many clusters, this step could take several
maintenance windows to complete. Upgrading ESX/ESXi hosts includes the following tasks:
a Use VMotion to move the virtual machines off of the ESX/ESXi host.
b Put the host into maintenance mode.
c Perform the upgrade.
