 Odoo Online
 ===========
 
-Requesting a test upgrade
-=========================
+Odoo databases can be manually upgraded directly from the main Odoo website. To upgrade an Odoo
+database, navigate to the `database manager <https://www.odoo.com/my/databases>`_ page and sign in.
 
-#. Go to your `database manager <https://www.odoo.com/my/databases/>`_
-#. Click on your profile icon and select *My Databases*.
+The database manager page displays all of the Odoo databases associated with the user's account. Any
+databases that are not already on the most recent version of Odoo display an **arrow in a circle**
+icon next to the database name, indicating that the database can be upgraded.

+=============

-      :alt: Selecting the action settings icon
+Click on the **arrow in a circle** icon to start the upgrade process. On the :guilabel:`Upgrade your
+database` pop-up, select the version of Odoo that the platform will be upgraded to. In the
+:guilabel:`Email to notify` field, enter an email address that will receive email notifications
+about the database upgrade.
 
-#. In the pop-up message that appears, select the target version and then :guilabel:`Test` as
-   purpose.
+There is also a :guilabel:`Purpose` section on the pop-up that is used to specify the reason for the
+upgrade. However, at this stage of the process, the only selectable option is :guilabel:`Test`, as
+Odoo requires users to create a test copy of the upgraded database before converting the actual
+database.
 
-   .. note::
-      The :guilabel:`Production` purpose doesn't appear if you didn't test your upgraded database at
-      least once.

-#. This triggers the automated upgrade process. A confirmation email is then sent to you with the
-   the link to the upgraded database or to provide information if the upgrade failed.
+After filling out the form, click the :guilabel:`Upgrade` button. The pop-up disappears and the
+database being upgraded shows a red :guilabel:`Upgrade in progress` tag next to its name. An email
+confirming that the upgrade is in progress is also sent to the email address specified on the
+pop-up.
 
-   .. note::
-      You can also see and access your test database from your *My Databases* page.

+
+Once the upgrade is complete, a new test database appears on the `database manager
+<https://www.odoo.com/my/databases>`_ page. To access the test database, click the drop-down arrow
+(:guilabel:`⯆`) to the left of the main database's name. Doing so makes the test version appear
+below it. Finally, click the green :guilabel:`Connect` button on the right side of the test
+version's row to go to the database.

+
+Except for being on the newer version of Odoo, the test database is an exact copy of the one being
+upgraded. It is important to do extensive testing in this database to ensure that the upgrade has
+not altered or corrupted any data, and that all workflows still proceed as expected.
+
+Production database
+===================
+
+After confirming the integrity of the new version, return to the `database manager
+<https://www.odoo.com/my/databases>`_ page. Once again, click on the **arrow in a circle** icon next
+to the database being upgraded. The :guilabel:`Upgrade your database` pop-up appears as before,
+except that there is now a :guilabel:`Production` option under the :guilabel:`Purpose` section.
+
+Select the :guilabel:`Production` option and then click :guilabel:`Upgrade` to begin the upgrade
+process. As before, a notification email is sent to the email address provided and a red
+:guilabel:`Upgrade in progress` tag appears next to the name of the database.
+
+After the upgrade is finished, the :guilabel:`Upgrade in progress` tag disappears and the database
+is upgraded to the version specified.
