Procedure
1 Upgrade ESXi hosts, cluster by cluster.
For instructions, see the VMware vSphere Upgrade Guide. If your clusters contain Virtual SAN datastores,
also see the chapter about upgrading the Virtual SAN cluster, in the Administering VMware Virtual SAN
document. This chapter contains a topic about upgrading ESXi hosts.
If you have many clusters, this step could take several maintenance windows to complete. Upgrading
ESXi hosts might include the following tasks:
a Use VMware vSphere
®
vMotion
®
to move the virtual machines off of the 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 Server, use vSphere Client to reconnect the host
to vCenter Server.
3 If you use View Composer, after all ESXi hosts are upgraded, on the vCenter Server host, restart the
View Composer service.
4 (Optional) Upgrade VMware
®
Tools™ and the virtual machines 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 VMware vSphere Upgrade Guide.
b Update VMware Tools, and upgrade the virtual machine hardware for virtual machines that will
be used as sources for remote desktops.
For step-by-step instructions if you plan not to use VMware vSphere
®
Update Manager™, see the
chapter about upgrading virtual machines in the VMware vSphere Virtual Machine Administration
document.
If you use VMware 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
VMware 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 remote desktops.
For step-by-step instructions if you plan not to use VMware vSphere
®
Update Manager™, see the
chapter about upgrading virtual machines in the VMware vSphere Virtual Machine Administration
document.
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 VMware vSphere
Upgrade Guide.
