 2. Everywhere you have used the database you have to replace ``$this->load->database();`` with ``$db = db_connect();``.
 3. If you use multiple databases use the following code to load additional databases ``$db = db_connect('group_name');``.
 4. Now you have to change all database queries. The most important change here is to replace ``$this->db`` with just ``$db`` and adjust the method name and ``$db``. Here are some examples:

 In CI4 you access uploaded files with ``$file = $this->request->getFile('userfile')``. From there you can validate if the file got uploaded successfully with ``$file->isValid()``.

 The new Model in CI4 has a lot of built-in methods. For example, the ``find($id)`` method. With this you can find data where the primary key is equal to ``$id``.
 Inserting data is also easier than before. In CI4 there is an ``insert($data)`` method. You can optionally make use of all those built-in methods and migrate your code to the new methods.
