Please correct me if I am wrong, but it appears to me that this upgrade does not require a database upgrade.I simply backed up my 1.10.1 installation, set the system to offline and uploaded the 1.10.4 files.I then copied my include/ost-config.php file from the old 1.10.1 installation into the new installation.I logged into the Staff portal and put the system back online.Finally I deleted the /setup directory and everything appears to be working perfectly.
