So far this upgrade seems to frustrating straight out of the box! We already run a VCSA (vCenter Server Appliance) and the process should be to automatically deploy a new VCSA and migrate the data from the old to the new and then power down the old. All from the Windows GUI installer.
But it fails to deploy with an unknown error.
If you save and view the installer log it becomes abundantly clear what the failure is. The installer is trying to issue a ‘date’ command at the current VCSA’s command line, and fails because it’s expecting a BASH shell and instead it is getting the default vCenter shell where the BASH shell is disabled.

In order to address the issue you need to change the default shell for the root user. It’s very easy to do, but will also require a password change.
Logon to the current VCSA using ssh as the root user. Enable the BASH shell and start the shell using:
shell.set --enabled True shell
Now change the root users default shell using
# chsh -s /bin/bash root
Now the installer should at least proceed through that part to deploy the image to the specified server.
