9 After upgrading ESXi hosts, you must reconnect the hosts to the vCenter Server and reapply the
licenses. See Chapter 10, “After You Upgrade ESXi Hosts,” on page 201.
10 Consider seing up a syslog server for remote logging, to ensure sucient disk storage for log les.
Seing up logging on a remote host is especially important for hosts with limited local storage. See
“Required Free Space for System Logging,” on page 52 and “Congure Syslog on ESXi Hosts,” on
page 203.
11 Upgrade your VMs and virtual appliances, manually or by using vSphere Update Manager, to perform
an orchestrated upgrade. See Chapter 11, “Upgrading Virtual Machines and VMware Tools,” on
page 205.
Mixed-Version Transitional Environments During vCenter Server Upgrades
You can upgrade a vCenter Single Sign-On instance that is deployed on a separate virtual machine or
physical server from vCenter Server to an externally deployed Platform Services Controller 6.0 while leaving
the vCenter Server instances that are using it at version 5.5.
If you upgrade an externally deployed vCenter Single Sign-On instance to an externally deployed
Platform Services Controller 6.0, the vCenter Server 5.5 instances that were using the vCenter Single Sign-On
instance are not aected. The vCenter Server 5.5 instances continue to operate with the upgraded
Platform Services Controller as they did before the upgrade without any problems or required
reconguration. vCenter Server 5.5 instances continue to be visible to vSphere Web Client 5.5, though
vCenter Server 6.0 instances are not visible to vSphere Web Client 5.5.
Mixed-version transitional behavior is the same for vCenter Single Sign-On instances deployed in
vCenter Server 5.5 for Windows environments and in vCenter Server Appliance environments.

N Mixed-version environments are not supported for production. They are recommended only during
the period when an environment is in transition between vCenter Server versions.
