Upgrade manual from 2.7.5 to 2.8.1

Hi All,

Is it possible to do a manual upgrade from 2.7.5 to 2.8.1 by doing a file compare and upload the new files?

The migration guide is not quite clear other then: CakePHP 2.8 is a fully API compatible upgrade from 2.7. This page outlines the changes and improvements made in 2.8.
