Updating existing portable install

[forschi]

Hi all,
Is there a "best practice" on how to upgrade a MM4 that is installed as "portable" on a USB?
I want to keep my library, settings, skins and addons (of course)

Is it as simple as installing to the same folder (over the old?)

Yes, making sure you select Portable Install in the installer.

As simple as that
I was about to, but the install warned me and I was not sure if I should ignore it or not.
But of course, a simple copy of the folder and test would work well

Thanks
