Having many Platform Services Controllers that replicate their infrastructure data, allows you to ensure
high availability of your system.
If an external Platform Services Controller with which your vCenter Server instance or
vCenter Server Appliance was initially registered, stops responding, you can repoint your vCenter Server or
vCenter Server Appliance to another external Platform Services Controller in the domain. For more
information, see “Repoint the Connections Between vCenter Server and Platform Services Controller,” on
page 122.
vSphere Upgrade Process
vSphere is a sophisticated product with multiple components to upgrade. For a successful vSphere upgrade,
you must understand the sequence of tasks required.
Upgrading vSphere includes the following tasks:
1 Read the vSphere release notes.
2 Verify that your system meets vSphere hardware and software requirements. See Chapter 2, “Upgrade
Requirements,” on page 33.
3 Verify that you have backed up your conguration.
4 If your vSphere system includes VMware solutions or plug-ins, verify that they are compatible with the
vCenter Server or vCenter Server Appliance version to which you are upgrading. See VMware Product
