Just a note here: if the site is on 2.0 Final, which is the same thing as 2.0.0, then you should not
have to uninstall and reinstall your mods.
In the admin centre there should be a link to the upgrade patch, with the standard warning notice. Clicking that link will enable you to upgrade from 2.0.0 to 2.0.1.
Once that is done, the main admin page will show another link and warning (because you are still one patch behind). Click that, and you'll be able to upgrade from 2.0.1 to 2.0.2.
Note that if you were to go straight from 2.0 Final to 2.0.2, that would require the use of an upgrade pack, and it would result in mods needing to be reinstalled. Doing the process via the two patches avoids having to mess with your mods.
