Initially, remove those two plugins from your folder and then check you have the correct version of the plugins for your version of moodle before attempting to reinstall them.
Although, there are two issues here - the moodle version those plugins require is 2015111600 - which is correct for Moodle3.0 BUT if that's the case, they can't have been on your 2.9 site (or at least not as that version of the plugin) as they would not install on 2.9 because of that version requirement.
My suggestion would be complete the site upgrade without those plugins, then reinstall the correct version of the plugin for your moodle.
