Upgrading ESX/ESXi hosts and virtual machines is the most time-consuming aspect of this middle phase of a VMware View upgrade.

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.

Complete the procedure described in Upgrade View Connection Servers in a Replicated Group.

Perform the ESX/ESXi upgrade preparation tasks listed in the vSphere Upgrade Guide.

1

Upgrade ESX/ESXi hosts, 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 might include 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.

d

Use VMotion to move the virtual machines back onto the host.

e

Perform post-upgrade tasks for ESXi hosts.

Every host must be a member of a cluster, as mentioned in the prerequisites.

2

If an upgraded host does not reconnect itself to vCenter, use vSphere Client to reconnect the host to the vCenter Server.

3

If you use View Composer, after all ESX/ESXi hosts are upgraded, on the vCenter Server host, restart the View Composer service.

4

(Optional) Upgrade VMware Tools on all parent virtual machines, virtual machine templates, and virtual machines that host View server components such as View Connection Server instances.

a

Plan for down time, as described in the vSphere Upgrade Guide.

b

Update VMware Tools, and upgrade the virtual machine hardware for virtual machines that will be used as sources for View desktops.

To use the Windows 7 3D rendering feature, available with View 5.0 and later, you must upgrade the virtual machine hardware to version 8.

If you use vSphere Update Manager, you can update VMware Tools and then the virtual hardware version in the correct order for all the virtual machines in a particular folder. See the vSphere Upgrade Guide.

5

(Optional) If you use full-clone desktops, on each virtual machine, upgrade VMware Tools and the virtual hardware for virtual machines that will be used as sources for View desktops.

To use the Windows 7 3D rendering feature, available with View 5.0 and later, you must upgrade the virtual machine hardware to version 8.

If you use vSphere Update Manager, you can update VMware Tools and then the virtual hardware version in the correct order for all the virtual machines in a particular folder. See the vSphere Upgrade Guide.
