I would like to share my experience about vCenter upgrade from 6.7 to 7.0. I was part of vSphere private bate tests like last couple of vSphere version. In my Lab environment I have upgraded vCenter.
Upgrades or migrations from vSphere 6.0 or earlier releases to vSphere 7.0 are not supported. Upgrades or migrations from vSphere 6.5 or later releases to vSphere 7.0 are supported.
If you have vSphere 6.0 or earlier, you must upgrade to vSphere 6.5 or vSphere 6.7 before upgrading to vSphere 7.0. vCenter Server 7.0 cannot manage ESXi hosts 6.0 or earlier.
Due to the deprecation of vCenter Server for Windows, vSphere 7.0 can only be deployed using the vCenter Server appliance.
You need the ISO file and moint it. Like previous versions browse the installer and run it on your system.
On the Introduction page you can see a yellow warning message which is warn you no external PSC anymore. If you have external PSC you have to convert it embeded first.

Start Stage 1
Add your existing / source vCenter server IP and port number. It is necessary becose during in the secund stage data will copy to target vCenter. Click connect to source button.
Type login credentials of ESXi host or vCenter server that manages the source appliance then add an ESXi host to target vCenter. Version of ESXi host (where target vCenter will deploy) need to be 6.5 or higher version.
Add the target vCenter server name and root password.
Select deployment size and datastore.
Configure temporary network settings. In stage 2, IP address will be changed automatically. On the target ESXi host have to exist an stanard vSwitch becouse Distributed switch portgroup not supported, installer can’t handle it.
Update1: Dejan have writen to Me that (below in comments) vDSwitch is supported just you need to use it ephemeral type. Thx Dejan! (I didn’t test it.)
Start Stage 2
Check warning messages and fix them if necessary.
In this screen you can choose level of data migration.
During the migration source vCenter will shutdown!!!
…and Done! Click the link and login to fresh new vCenter 7 server.
As you can see picture below, flash disappeared. HTML5 login option only.
The whole process was not take more than 1-1,5 hour to me in my home lab. Installer was easy manage and similar like in previous version. Here some advice in bullet point:
- If you use external PSC you have to convert it first, check KB article
- Your target host have to v. 6.5 or higher
- Use stanard vSwitch or vDswitch emphemeral type on the host where you deploy the target vCenter server
- Make sure you have an working backup from source vCenter
- One point of Stage 2 your source vCenter will shutdown
