You can upgrade your externally deployed vCenter Single Sign-On 5.5 to an externally deployed Platform Services Controller instance by using the vCenter Server for Windows installer.
If you are upgrading an externally deployed vCenter Single Sign-On 5.5 to an externally deployed Platform Services Controller in a mixed version environment, any vCenter Server 5.5 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 more information about how vCenter Single Sign-On affects your upgrade, see How vCenter Single Sign-On Affects Upgrades.
- For information on vCenter Server behavior in mixed version environments, see Mixed-Version Transitional Environments in vCenter Server for Windows Upgrades.
- For information on deployment options, see vCenter Server Deployment Models.
- Your current vCenter Single Sign-On must have been installed on a separate virtual machine (VM) or physical server from your vCenter Server instance.
- Verify your configuration meets the upgrade requirements, see vCenter Server for Windows Requirements.
- Complete the preparation to upgrade tasks. See Before Upgrading vCenter Server
- Verify that you have made a backup of your vCenter Server configuration and database.
- To verify that the VMware Directory Service is in a stable state and can stop, manually restart it. The VMware Directory service must stopped for the vCenter Server upgrade software to uninstall vCenter Single Sign-On during the upgrade process.
- Download the vCenter Server Installer. See Download the vCenter Server for Windows Installer
- Download the vCenter Server for Windows ISO file. Extract the ISO file locally, or mount the ISO file as a drive.
- In the software installer, double-click the autorun.exe file to start the installer.
- Select vCenter Server for Windows and click .
The installer 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.

You can create or join a Platform Services Controller instance.
Replication information is retained during the upgrade.The vCenter Single Sign-On 5.5 domain System-Domain is migrated to the new domain you choose.
- If this is the first or primary vCenter Single Sign-On instance, upgrade it to a new standalone Platform Services Controller instance by configuring a new vCenter Single Sign-On domain name and site name.
- If you have two or more vCenter Single Sign-On instances and this is the second or an additional vCenter Single Sign-On instance, join it to the vCenter Single Sign-On site of the primary Platform Services Controller to enable replication.
- Configure the ports and click
. Verify that ports 80 and 443 are free and dedicated, so that vCenter Single Sign-On can use these ports. Otherwise, use custom ports during installation.The installer checks the availability of the selected ports and displays an error message if a selected port cannot be used.
