The following table explains how XperienCentral handles a layout switch and how fields and loops from one layout are mapped to another (or not). The mapping logic takes into account what is available in the structure of the layout being switched to and then applies the rules described below.
| Field | Available field | Mapped |
| prefilled field | empty field | Determined by the field type mapping rules described below. |
| empty field | prefilled field | Determined by the field type mapping rules described below. |
| prefilled field | prefilled field | Determined by the field type mapping rules described below. |
| rich text | rich text single line | No |
| rich text | single line (flat) | No |
| rich text single line | rich text | Yes |
| rich text single line | single line (flat) | No |
| single line (flat) | rich text | Yes |
| single line (flat) | rich text single line | Yes |
| Field with name A | Field with name A | Determined by the field type mapping rules described above. |
| Field with name A | Field with name B | Determined by the field type mapping rules described above. |
| Prefilled field with name A | Prefilled field with name A | Determined by the field type mapping rules described above. |
| Prefilled field with name A | Prefilled field with name B | Determined by the field type mapping rules described above. |
| Loop | Available loop | Mapped |
| Single loop | Multiple loops | The single loop is mapped to the first of the multiple loops. |
| Multiple loops | Single loop | The first of the multiple loops will be mapped to the single loop. The rest of the loops will be lost. |
| Singe or Multiple loops | No loops | No - all loops will be lost. |
