How to Determine if an Application is a Legacy Application

1. View the application's app.xml file.

   The app.xml file is located in the application's WEB-INF directory.

2. Examine the registrationInfo tag in the app.xml file.

   For a legacy application, the registrationInfo tag is a version 2.x. For example, registrationInfo version="2.2.4".

   For a current application, the version in the registrationInfo tag is at least 3.0. For example, registrationInfo version="3.0".
