Have not done it yet, but should be able to upgrade DIY. My last upgrade was needed by support due to SQL 32bit to 64bit. Now all practices on v12 and above should be on SQL 2016 which is only 64bit. The installer for v12.4 will have a newer SQL express version. Just follow the self upgrade directions on the client portal site where you get the installer and tuner. I plan on upgrading soon. I run AC in a virtual machine which makes rolling back if something goes wrong very easy.
