Recommended Order & Requirements

The order

Always work in this order: users → articles/categories → menus → modules -- for both export and import. Later imports rewrite their references through ID maps recorded by earlier ones; the importer warns when it detects a wrong order and tells you what to re-import.

Requirements per step

• Menus: component-type items need their component installed on the target (e.g. com_virtuemarket-style extensions); missing ones are skipped with a warning, never imported broken.
• Modules: module types must exist on the target; unrecognized types are skipped with a warning.
• Articles: nothing required -- categories are created or mapped automatically.
