Case 1: Focal Point field under Image Wrapper content type has to be preserved
Assume you have a destination content type: Image Wrapper with a field Focal point that is a JSON field. See content model:
This field doesn't exist in the source endpoint. So the requirement in this case, is to be able to sync all the other fields without losing the Focal point value.
Step 1: Create a job to sync the content type: Image Wrapper
First we create the job to sync the content type: Image Wrapper from the source endpoint to the destination endpoint.
Step 2: Set up the content mapper
Next we set up the content mapper. Go to Field Locking section and set the Destination Locked Field property to focalPoint (the id of the field in the destination endpoint).
