Here I’m upgrading from version 6.0 to 6.5, the process creates a new vCenter appliance, then migrates all your settings into it, finally it then shuts down the old appliance and brings up the new one.
vCenter 6.5 Upgrade Paths
|From Version||To Version 6.5|
ESX (Host) Versions Supported by vCenter 6.5

Note: If you are on vSphere 4 (or earlier), you need to upgrade to version 5.5 first;
Before Starting: Backup or snapshot your existing vCenter appliance.
Download the ISO file for the vCenter Appliance from VMware, and mount it on a machine that has network connectivity to the vCenter Appliance, and the ESX host that it is hosted on. Then navigate to;
And run the installer.exe file.
Agree > Next.
Put in the details for your existing vCenter Appliance, and the ESX host it is mounted on > Next.
Note: You can get those details from either the VI client, or the web client;
Accept the certificate warning, (if you have installed trusted certificates, as per the following article, you wont see this message) > Yes.
Enter the details for the NEW ESX Server, this can obviously be the same as the source one, I’m just moving it to the newer of my two hosts > Next.
You may then get a certificate warning from the ESX box that vCenter is to be hosted on. (If you have installed trusted certificates, as per the following article, you wont see this message) > Yes.
Enter the VM name for the new vCenter appliance. (Note: That’s VM name NOT hostname, it will get that, (post migration), from the source vCenter appliance) > Next.
WARNING: This password has to be complex, and WONT get overwritten with the migration process. My root password was not complex enough, so post migration I had to go back into the appliance, and change the password back. So take a note of the password you use.
Select your deployment sizes, (as shown in the examples) > Next.
Select a datastore for the appliance to live on > Next.
Supply some IP details for the new appliance to use, (until the settings are migrated from your old one) > Next.
Read the summary > Finish.
The new appliance will be created and powered on, (this can take a while), when complete > Continue.
Commence stage 2, (migrate your settings into the new appliance) > Next.
The server details will be ‘Pre Populated’ from stage one > Next > You may receive a warning about DRS, either disable DRS on the cluster or (as suggested) ensure it’s NOT set to fully automated > OK > Configuration > Next.
I personally always untick the CEIP > Next.
Tick to confirm you have backed up vCenter > Finish.
Time for a coffee again, from this point forward everything is automated > when complete > Close.
The new vCenter you can now manage with the, (much improved) HTML5 management portal.
