Plan for script to migrate a page from DjangoCMS Cascade to Aldryn Bootstrap plugin

migration-plan-pseudo-code.py

# Usecase: I have a DjangoCMS website with content and everything. It is using DjangoCMS Cascade plugin and I'd like 
# to start using Aldryn Bootstrap plugin. I'd like to have a script that migrates all my content from one plugin to 
# the other, since I don't want to do manually.

# Assuming aldryn_bootstrap is already installed
# The hard part is to deal with Grid elements, because it has multiple levels. Other stuff (like buttons) can just be replaced

for container_plugin in all_bootstrap_containers_plugins:
    for row_plugin in container_plugin.get_children().filter(row_plugin=True).order_by(position):
        # Create left sibling of container_plugin
        container_plugin.add_sibling('left', instance=new_row_plugin)
        # For each column in row_plugin, create a new column in newly created row
        for column in row_plugin.get_children().order_by(position):
            new_row_plugin.add_child(instance=new_column)
            # Copy the existing content into the new column
            for plugin in column.get_children():
                plugin.move(target=new_column, 'last-child')
    # Delete the container and all its descendants
    container_plugin.delete()
