+Migration
+#########
+
+This section helps you migrate from PyVista plotters to the Ansys Tools Visualization Interface plotters.
+It consists of two major topics:
+
+- `Code migration`_
+- `Documentation configuration migration`_
+
+Code migration
+==============
+This topic explains how to migrate from PyVista plotters to the new Ansys Tools Visualization Interface plotters. Because cases vary greatly, it provides a few examples that cover the most common scenarios.
+
+Replace PyVista plotter code with Ansys Tools Visualization Interface plotter code
+----------------------------------------------------------------------------------
+If you only need to plot simple PyVista meshes, you can directly replace your PyVista plotter code with the Ansys Tools Visualization Interface plotter code.
+On top of common PyVista functionalities, the Ansys Tools Visualization Interface plotter provides additional interactivity such as view buttons and mesh slicing.
+
+The following code shows how to do the plotter code replacement:
+
+- PyVista code:
+
+.. code-block:: python
+
+    import pyvista as pv
+
+    # Create a PyVista mesh
+    mesh = pv.Cube()
+
+    # Create a plotter
+    pl = pv.Plotter()
+
+    # Add the mesh to the plotter
+    pl.add_mesh(mesh)
+
+    # Show the plotter
+    pl.show()
+
+- Ansys Tools Visualization Interface code:
+
+.. code-block:: python
+
+    import pyvista as pv
+    from ansys.tools.visualization_interface import Plotter
+
+    # Create a PyVista mesh
+    mesh = pv.Cube()
+
+    # Create a plotter
+    pl = Plotter()
+
+    # Add the mesh to the plotter
+    pl.plot(mesh)
+
+    # Show the plotter
+    pl.show()
+
+
+Convert your custom meshes to objects usable by the Ansys Tools Visualization Interface plotter
+-----------------------------------------------------------------------------------------------
+
+Your custom object must have a method that returns a PyVista mesh and a method that exposes a ``name`` or ``id`` attribute of your object:
+
+.. code-block:: python
+
+    class CustomObject:
+        def __init__(self):
+            self.name = "CustomObject"
+            self.mesh = pv.Cube(center=(1, 1, 0))
+
+        def get_mesh(self):
+            return self.mesh
+
+        def name(self):
+            return self.name
+
+
+You then need to create a :class:`~ansys.tools.visualization_interface.types.mesh_object_plot.MeshObjectPlot` instance that relates the PyVista mesh with your custom object:
+
+.. code-block:: python
+
+    from ansys.tools.visualization_interface import MeshObjectPlot
+
+    custom_object = CustomObject()
+    mesh_object_plot = MeshObjectPlot(
+        custom_object=custom_object,
+        mesh=custom_object.get_mesh(),
+    )
+
+With this, you can use the Ansys Tools Visualization Interface plotter to visualize your custom object. It enables interactivity such as picking and hovering.
+
+
+Customize the PyVista backend
+-----------------------------
+
+You can customize the backend of the Ansys Tools Visualization Interface plotter to enable or turn off certain functionalities. The following code shows how to enable picking:
+
+.. code-block:: python
+
+    from ansys.tools.visualization_interface import Plotter
+    from ansys.tools.visualization_interface.backends import PyVistaBackend
+
+    backend = PyVistaBackend(allow_picking=True)
+
+    # Create a plotter
+    pl = Plotter(backend=backend)
+
+    # Add the MeshObjectPlot instance to the plotter
+    pl.plot(mesh_object_plot)
+
+    # Show the plotter
+    pl.show()
+
+If you want to customize the backend even more, you can create your own backend by inheriting from the :class:`~ansys.tools.visualization_interface.backends.pyvista.PyVistaBackendInterface` class
+and implementing the required methods:
+
+.. code-block:: python
+
+    @abstractmethod
+    def plot_iter(self, plottable_object: Any, name_filter: str = None, **plotting_options):
+        """Plot one or more compatible objects to the plotter.
+
+        Parameters
+        ----------
+        plottable_object : Any
+            One or more objects plot.
+        name_filter : str, default: None.
+            Regular expression with the desired name or names to include in the plotter.
+        **plotting_options : dict, default: None
+            Keyword arguments. For allowable keyword arguments, see the
+            :meth:`Plotter.add_mesh <pyvista.Plotter.add_mesh>` method.
+
+        """
+        pass
+
+
+    @abstractmethod
+    def plot(self, plottable_object: Any, name_filter: str = None, **plotting_options):
+        """Plot a single object to the plotter.
+
+        Parameters
+        ----------
+        plottable_object : Any
+            Object to plot.
+        name_filter : str
+            Regular expression with the desired name or names to include in the plotter.
+        **plotting_options : dict, default: None
+            Keyword arguments. For allowable keyword arguments, see the
+            :meth:`Plotter.add_mesh <pyvista.Plotter.add_mesh>` method.
+
+        """
+        pass
+
+
+The rest of the methods are implemented for you. This ensures that while you can customize what you need for plotting,
+the rest of the functionalities still work as expected. For more information, see the backend documentation. If you
+need to even go further, you can create your own plotter by inheriting from the :class:`~ansys.tools.visualization_interface.backends._base.BaseBackend` class and implementing the required methods,
+although this may break existing features.
+
+Customize the picker or hover behavior
+--------------------------------------
+You can customize the picker of the Ansys Tools Visualization Interface plotter to decide what happens when you pick or hover over an object.
+For example, if you want to print the name of the picked object, you can do it as described in the :ref:`sphx_glr_examples_00-basic-pyvista-examples_custom_picker.py` example.
+
+Use the PyVista Qt backend
+--------------------------
+You can use the PyVista Qt backend with the Ansys Tools Visualization Interface plotter. To do this, you must set the PyVista backend to Qt
+before creating the plotter:
+
+.. code-block:: python
+
+   cube = pv.Cube()
+   pv_backend = PyVistaBackend(use_qt=True, show_qt=True)
+   pl = Plotter(backend=pv_backend)
+   pl.plot(cube)
+   pl.backend.enable_widgets()
+   pv_backend.scene.show()
+
+You can then integrate the plotter into a PyQt or PySide app by disabling the ``show_qt`` parameter.
+For more information about this, see the `PyVista documentation <https://qtdocs.pyvista.org/>`_.
+
+
+Documentation configuration migration
+=====================================
+
+This topic explains how to migrate from the PyVista documentation configuration to the new Ansys Tools Visualization Interface documentation configuration.
+
+1. Add environment variables for documentation:
+
+.. code-block:: python
+
+    os.environ["PYANSYS_VISUALIZER_DOC_MODE"] = "true"
+    os.environ["PYANSYS_VISUALIZER_HTML_BACKEND"] = "true"
+
+2. Use PyVista DynamicScraper:
+
+.. code-block:: python
+
+    from pyvista.plotting.utilities.sphinx_gallery import DynamicScraper
+
+    sphinx_gallery_conf = {
+        "image_scrapers": (DynamicScraper()),
+    }
+
+3. Add PyVista viewer directive to extensions:
+
+.. code-block:: python
+
+    extensions = ["pyvista.ext.viewer_directive"]
+
+4. Make sure you are executing the notebook cells:
+
+.. code-block:: python
+
+    nbsphinx_execute = "always"
