Update from RC to Stable, or need to reinstall Stable when available?

[Eddystone]

I'm looking to install Lite on a friend's computer that is located at a great distance. I won't be around to install the upcoming new Stable version on that computer.

If I install Linux Lite 6.6 RC1 now, can the system be simply updated from the installed RC1 to the Stable version when it's ready? Or will the Stable version require a clean install?

Thanks.
