This section explains how you can migrate your V4 models to V5.
To explain the process briefly, you have to convert the classes and attributes in your V4 Project Registration Model to an XML file and ftp it to a V5 directory. You have to do the same with the classes and attributes in your V5 Feature Dictionary.
A tool compares these two XML files and then imports the classes and attributes that do not exist in V5 from the V4 XML file and makes them available to you in V5.
