-## Configure Left Sidebar
-
-To keep UX/UI similar across different Qiskit packages we strongly encourage the following structure for you sidebar, which can be set in the toctree of your `index.rst`:
-
-```rst
-.. toctree::
-  :hidden:
-
-   Documentation Home <index>
-   Getting Started <getting_started>
-   Tutorials <tutorials/index>
-   How-to Guides <how_to/index>
-   API Reference <apidocs/index>
-   Explanations <explanations/index>
-   Release Notes <release_notes>
-   GitHub <https://github.com/your-repo>
-```
-
-The above toctree will render a sidebar that looks like the image below:
-
-<img width="626" alt="Screenshot 2023-02-09 at 12 13 52 PM" src="https://user-images.githubusercontent.com/23662430/217783745-43623c4f-897a-4a96-9d05-137d881ddb3f.png">
-
-Each item in the toctree corresponds to a single `.rst` file, and can use internal links or external. External links will have a "new tab" icon rendered next to them.
-
-<img width="257" alt="Screenshot 2023-02-09 at 12 14 45 PM" src="https://user-images.githubusercontent.com/23662430/217783918-ae4fc420-43c5-4d56-b135-4f12043cd881.png">
-
-In addition to the pages in the toctree, the sidebar also adds:
-- (optional) a separate dropdown menu *at the top* with different languages, but only if you have a `translations_list` setup in your `html_context` in your `conf.py` corresponding logic in a `version_utils.py`.
-- (optional) a dropdown *at the bottom* with links to previous releases, if you have a `version_list` setup in your `html_context` in your `conf.py` and corresponding logic in a `version_utils.py`.
-
-### Add Expandable Items to Sidebar
-
-You may want to configure your documentation to include expandable items in the sidebar, for example:
-
-<img width="467" alt="Screenshot 2023-02-09 at 12 29 13 PM" src="https://user-images.githubusercontent.com/23662430/217787248-8017da57-c347-4eea-a220-8515ca2ce8d6.png">
-
-To configure your documentation to use exapandable sidebar headings like the example above you must do the following:
-1. Add a `expandable_sidebar` variable to the `html_context` object in your `conf.py` and set the value to `True`:
-    ```python
-    html_context = {
-        'expandable_sidebar': True
-    }
-    ```
-2. Refactor the `toctree` in your `index.rst` to separate your pages into different sections. Sections that include a `:caption:` directive will be turned into expandable sidebar sections, with the caption forming the title of the dropdown. for example, to render the expandable sidebar shown above your `toctree` in your `index.rst` should look like this:
-    ```rst
-    .. toctree::
-    :hidden:
-
-    Documentation Home <index>
-    Getting Started <get_started>
-
-    .. toctree::
-    :hidden:
-    :caption: Tutorials
-
-    Tutorial 1 <tutorials/01>
-    Tutorial 2 <tutorials/02>
-    Tutorial 3 <tutorials/03>>
-    All Tutorials <tutorials/index>
-
-    .. toctree::
-    :hidden:
-    :glob:
-    :caption: How-to Guides
-
-    how_tos/*

-    .. toctree::

-    Release Notes <release_notes>
-    GitHub <https://github.com/your-repo>
-    ```
-
-
-*Tip: if you want to add all files in a sub-directory to your expandable dropdown section you can use the `:glob:` directive instead of listing out each page (see example above for the How-to Guides, API Reference and Explanations sections). This will list out each page in alphabetical order, so if you want a specific order you will need to list the pages out individually in the `toctree` (see example above for the Tutorials section)*

+## Migrate from old Pytorch theme to new theme
+
+In qiskit-sphinx-theme 1.13, we migrated to a new Sphinx theme based on Furo, which is used by pip, Black, and attrs documentation. See https://github.com/Qiskit/qiskit_sphinx_theme/issues/232 for the motivation.
+
+qiskit-sphinx-theme 1.13 continues to support the legacy Pytorch theme, but support will be removed in version 2.0.
+
+To migrate:
+
+1. In `conf.py`, set `html_theme = "qiskit"` rather than `"qiskit_sphinx_theme"`.
+2. In `conf.py`, remove all `html_theme_options`.
+3. In `conf.py`, remove `expandable_sidebar` from `html_context`, if set.
+4. If `expandable_sidebar` was enabled, then update your `index.rst` files. The new theme always has expandable sidebars. Before, you had to have a dedicated `.. toctree::` directive for each expandable folder, along with the `:caption:` option set to the folder name. To migrate, consolidate all of your `.. toctree::` directives into one. Alternatively, you can keep the separate `.. toctree::` entries; the `:caption:` will render as a top-level header and the folder contents will be expanded.
+5. Render the docs and check that everything looks how expected. If not, please open a GitHub issue or reach out on Slack for help.
+
+Reminder: you do not have to migrate to the `qiskit` theme until qiskit-sphinx-theme 2.0. For example, you can migrate but rollback to `qiskit_sphinx_theme` if you discover there is an issue.
+
+## Tip: suggested site structure
 
-If you do not enable analytics no data will be collected and the `Was this page helpful?` component will not show.
+To keep UX/UI similar across different Qiskit packages, we encourage the following structure for you sidebar, which can be set in the toctree of your `index.rst`:

+Each item in the toctree corresponds to a single `.rst` file, and can use internal links or external. External links will have a "new tab" icon rendered next to them.
