After update php need running 'sh /script/fixphpfpm; sh /script/restart-services' if using php-fpm.
Sometimes switch php-branch not work because php-fpm installed and or need switch external php module manually. It's not Kloxo-MR but limitation/bug from 'yum replace' method from IUS.
For me it does not work php-fpm.
