Now that you've created and published your simple extension, let's look at how you can promote it to other environments, and how you can delete it once your setup testing is complete. To do both tasks, you'll use the Manage Extension Lifecycle page.

1. From the menu in the Designer's header, click Extension Lifecycle.

   You should now see the Manage Extension Lifecycle page, which lists all the environments that are available for you to deploy to.

   At this point in your setup testing, you'll probably see only your DEV environment. You can create additional environments (for example, for your TEST and PROD instances) from the Environment's page. See Add an Oracle Cloud Application Instance to an Environment and Add the Oracle Cloud Application's Production Instance to an Environment. Or, you can add a new environment right from this page (see step 2).

   Note:

   If you see a Provide Credentials button next to an environment, you must first sign in before you can deploy your changes to it.
2. To add a new Oracle Cloud Applications environment right from this page:
   1. Click Add Environment.
   2. In the Add Environment panel, enter basic environment details, such as the environment's base URL, environment name, and user name and password for the target Oracle Cloud Applications instance.
      You can add any environment as long as the authentication method for its Oracle Cloud Applications instance is OAuth.
   3. Click Add.
3. Once you've got an environment set up, you can now try deploying your simple extension to it:
   1. Find your simple extension and click .
   2. Choose the environment that points to the instance you want to deploy to.
   3. Click Deploy.
4. As this was just a simple test and not a real extension, you may want to remove it. To delete the extension, click .
   Deleting an extension restores your application to its original state.
