There is WAY more to do in such an upgrade than just replacing some files. You should read up on the upgrade tools, look at the migration guides, and consider upgrading to the 3.x line (4.0 is getting close to release) instead of 2.x.

You need to start on the migration guide (https://book.cakephp.org/2.0/en/appendices.html) and upgrade each step at a time starting with 1.3 to 2.0 (https://book.cakephp.org/2.0/en/appendices/2-0-migration-guide.html)
