You must first complete the previous section by importing your project into Blender 3.6 LTS. Currently, it is not possible to import directly into Blender 4.X due to core changes in Blender. Although we recommend continuing with Blender 3.6, you can still follow these steps to migrate your project to the version of your choice.
Once your simulation has been imported into Blender 3.6 LTS successfully:
1.Save your project (you may save it at the same location as before)
2.Close Blender 3.6 LTS and open your latest Blender 4.X install
3.Simply open your project and save it




You should now be able to run your simulation in the Blender version of your choice.
