Installing with tmsh automatically copies active config?

I am going through the process of upgrading an F5 BIG-IP and decided to do it from the cli with tmsh this time. Previously when using the UI you had the option when setting the boot location to "Install Configuration [yes/no]" and "Source Volume [select list]".

I read this article https://support.f5.com/csp/article/K13438 that seems to state doing the install via tmsh the config is automatically copied based on the values of LiveInstall.MoveConfig and LiveInstall.SaveConfig which default to enable.

Is this correct and installing an upgrade from tmsh automatically will copy the current config to the new volume?
