how to import layout from mx7 to mx8?

Does anyone know why layouts and building blocks are version bound? It doesnt make any sense to me why containers with classes need such strict rules around them. also does anyone know how to import mx7 layouts/pages into mx8?

As explained in the error message, you need to:

  1. import your layouts in Mendix Modeler 7.23.0 or higher
  2. export your layouts from 7.23.0 or higher
  3. import your layouts to Modeler 8
