+
+You can now begin using your new organization to test Login with SSO. For self-hosted and on-premise users, you will need to do this as well to generate a new license file. We recommend using a separate Bitwarden instance for testing Login with SSO for self-hosted and on-premise users.
+
+Once you have completed your Trial and testing, [contact customer success](https://bitwarden.com/contact) to upgrade your current Enterprise Plan. You can also cancel your Trial Organization subscription via the [Bitwarden Web Vault](https://vault.bitwarden.com/).
