6.5.1

n
vSphere Web Client 5.5 shows vCenter Server instances only, not 6.5 instances.
When you upgrade the external vCenter Single Sign-On 5.5 instance to an external
Platform Services Controller 6.5 instance, and all vCenter Server 5.5 instances to version 6.5, none of the
vCenter Server instances are affected. They continue operating with the Platform Services Controller as
they did before the upgrade, without any problems or required action.
The transitional order and behavior are the same for vCenter Server 6.0 environments when upgrading or
migrating to vCenter Server 6.5 environments. The vCenter Server 6.0 instances continue operating with
the Platform Services Controller 6.5 instance as they did before the upgrade or migration, without any
problems or required action.
The only action required for a mixed-version environment after transition is a restart of any legacy
vSphere Web Client instances if they will be used to view vCenter Server instances that are not yet
upgraded or migrated.
