We have used cakephp 2.x in one of our older projects and had customized the framework according to the project’s need. Now we would like to migrate one of its plugins into another project which we have just started building in cakephp 3.3. I have searched the internet but all the help I get is about migrating an uncustomized cakephp 2.x. How do we go about doing that? One of the major issues we are facing is to convert app::uses to suit the new application. A lot of core files have changed from 2.x to 3.3. How do we go about doing that.
