Migration from CakePHP2.x to CakePHP 3.x


I want to upgrade the project with cakephp version 2.6 and PHP 5.3 to PHP 7.2 and cakephp 3.x. I tried to migrate by using the ugrade tool present in github and followed the steps written on the document. After the upgrade, the source code present in version 2.6 got modified. Now, do we need to move the files to new folder (code with version 3)??

Am not getting what to do after upgrade process. Please help me to continue further.

Please advice.
