After releasing the vSphere 6.5 I was planning to migrate the old VMware vSphere 5.5 environment to vSphere 6.5 environment. There are lots of reading and searching involved and you can find all the information form VMware Documentation site. There are few things to check before the upgrade existing environment and recommend to read the Moving from a Deprecated to a Supported vCenter Server Deployment Topology Before Upgrade or Migration. Also verify your existing hardware support to the upgrade in the VMware Compatibility Guide.
Verify the Hardware requirements according the environment that you are going to manage. Refer the VMware Documentation
Upgrading the Single Sign-on server
- Windows version
- Minimum processor requirements
- Minimum memory requirements
- Minimum disk space requirements
- Permissions on the selected install and data directory

Change the required ports upon your requirements, I’m leaving the default ports and click “Next” to move forward
Select the the Installation,Store data and export data directories in the next step, click “Next” to continue
If you need you can join the “Customer Experience Improvement Program” here, I’m leaving the option unchecked.
Verify that You have backed up the Single Sign-on Server before the upgrade. That’s the option that I mentioned earlier. Click on “Upgrade” to start the upgrade process
This will complete the upgrade of your Single Sign-on to a Platform Service Controller. Click “Finish” once it completes the upgrade process
Upgrading the vCenter Server
Mount the vCenter 6.5 iso to the vCenter server and run the installer , select “vCenter Server for Windows” and click on “Install”
Click “Next” to continue
Accept the EULA
Type your Single Sign-on password, click “Next” to continue. It will run a pre-upgrade check again
Type the Single Sign-on password and verify the HTTPS port for the SSO service
Accept the SSO Certificate Validation
Syslog, Core Dump and Auto deploy ports can be seen in the next step. I leave them as defaults
You can see the directories for the Installation, Store the data and the Export the existing data
Accept the vCenter and DB backup requirement to start the upgrade, Click “Upgrade” to start the upgrading process.
Make sure take a backup of the vCenter and the DB for the safe side rather than checking the check box.
It will start the vCenter upgrade and you can access the vCenter in the web console. vCenter 6.5 does not support for the C# fat client.
