To import content from GatherContent, you'll need to set up mappings between templates in GatherContent and page types in Kentico and their corresponding fields. Follow these steps to map your templates:

The manage template mappings screen will appear.

Clicking on the "Add Mappings" button will bring up the Field Mappings dialog. The Field Mappings dialog lets the user specify which templates and fields should be mapped.

First, users should specify a name for the mapping. The mapping name will be used to distinguish mappings on import dialogs.

Specify the GatherContent project and Template you want to map and choose the corresponding Kentico page type.

Once you’ve completed the previous steps, all tabs and fields will be dynamically populated. The user can now map GatherContent fields to Kentico fields. The Content Editor can map the required fields by selecting an Kentico field in the corresponding dropdown on the right-hand side of the screen.

Only fields that are possible to map are displayed in the dropdowns. For example, it is not possible to map a text field from GatherContent to an image field in Kentico.

The plug-in supports many-to-one field mappings for text and guidelines field types. This means, that it is possible to map, for example, two GatherContent fields into one Kentico field. The content of such fields will be concatenated and placed in the Kentico field.

Please check the mappings table that shows all the supported field mappings:
