Resolution:
You can achieve this in one of 2 ways

  - Manual.  Users can simply create a new MB 3.2 transform which implement the same business logic using the 3.2 Model.
  - Migration Helper.  MB 3.2 now includes a Migration helper which will help with some of the conversion.  PLEASE NOTE: This is a helper utility not a conversion tool and will often require user intervention in the converted transform.  Please refer to the MB User's Guide for more detailed information on this migrator helper.
