Perform the ESX/ESXi upgrade preparation tasks listed in the vSphere Upgrade Guide.
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.
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 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.
Each virtual machine must be rebooted three times.
b Update VMware Tools, and upgrade the virtual machine hardware to version 8 for virtual machines
that will be used for remote View desktops, or upgrade to version 7 for virtual machines that will be
used for local mode View desktops.
To use the Windows 7 3D rendering feature, available with View 5.0, 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 If you use full-clone desktops, on each virtual machine, upgrade VMware Tools and the virtual hardware
to version 7 for local mode View desktops, or upgrade to version 8 for remote View desktops.
To use the Windows 7 3D rendering feature, available with View 5.0, 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.
