In a mixed version environment, any vCenter Server 6.0 instances continue to operate with the upgraded
Platform Services Controller exactly as they did with the vCenter Single Sign-On without any problems or
required actions. For information on vCenter Server behavior in mixed version environments, see
Upgrade or Migration Order and Mixed-Version Transitional Behavior for Multiple vCenter Server Instance
Deployments.

Procedure
1 Download the vCenter Server for Windows ISO file. Extract the ISO file locally, or mount the ISO file
as a drive.
2 In the software installer, double-click the autorun.exe file to start the upgrade.
3 Select vCenter Server for Windows and click Install.
The software runs checks in the background to discover your existing vCenter Single Sign-On
settings and notify you of any problems that can affect your upgrade process.
The vCenter Server installer opens to the Welcome page.
4 Verify the detected information and upgrade path.
If you see a dialog box identifying missing requirements instead of a Welcome screen, follow the
instructions in the dialog box.
5 Review the Welcome page and accept the license agreement.
6 Enter the credentials for the administrator@vsphere.local. The user must be
administrator@your_domain_name.
The installer runs pre-upgrade checks in the background to detect any issues that can cause the
upgrade to fail. You might receive a warning if the old certificates do not meet current VMware
security standards.
