Pre-upgrade checks will run, and will inform you if you have any errors or warnings.
If any errors or warnings occur, you can review the VMware KB or vSphere documentation site for more information.

During the installation, you will be asked for what historical data you want to import from the existing VCSA.

If you want to join the Customer Experience Improvement Program (CEIP) then check the box. CEIP helps with proactive support and metrics.

The last step in the wizard is to verify the information you have entered and that the existing VCSA have been backed up.

Check the box and hit to the Finish button to complete the stage 2.

A prompt window will appear with warning and it will show you that during this process the source vCenter Server appliance will be shutdown.

Click to Ok.
