What happens to the main menu after the upgrade?

Our main menu, the one with the tabs, has a few custom tabs that were created in the admin section with the page builder. These lead to subdirectories within our primary domain which is also home of our D7 community. Those subdirectories will obviously remain untouched during a 7.0.1 upgrade but I'm wondering about the menu tabs themselves? Will our own menu tabs remain in place or will all of the menu tabs be replaced with new ones during the upgrade?
