Upgrade of PXC is similar to upgrading MySQL instance. Shutdown MySQL, install the latest PXC version via yum insall and start MySQL. I would suggest to upgrade one node at a time and monitor it and it would be best to test you upgrade procedure you some test server first before doing it on production you can check it here for cluster node restart
