I run Easyblog and Komento on Joomla 2.5. I'm going to upgrade to Joomla 3.3 soon now and I'm wondering if I need to uninstall Easyblog and Komento before I upgrade?

So I would uninstall Easyblog and Komento, then upgrade to Joomla 3.3 and then install Easyblog and Komento again. Or can I upgrade to Joomla 3.3 without having to uninstall and install Easyblog and Komento?
