+title: Classic vs Enhanced Automated Builds
+---
+
+With the launch of the new Docker Hub, we are introducing Enhanced Automated Build.
+
+Automated builds created using the old Docker Hub are now Classic Automated Builds, and automated builds created 
+using the old Docker Cloud are now Enhanced Automated Build. 
+
+All new automated builds created going forward will be Enhanced Automated Build. If you are creating an Enhanced
+Automated Build for the first time, see [docs](index.md#configure-automated-build-settings).
+
+In the coming months, we will gradually convert Classic Automated Builds into Enhanced Automated Builds. This should
+be a seamless process for most users.
+
+
+## Managing Classic Automated Builds
+
+You can manage both Classic and Enhanced Automated Builds from the **Builds** tab
+
+Repository with Classic Automated Build:
+
+![A Classic Automated Build dashboard](images/classic-vs-enhanced-classic-only.png)
+
+You can configure build settings pretty much the same way as the old Docker Hub.
+
+If you have previously created an automated build in both the old Docker Hub and Docker Cloud, you can switch between 
+Classic and Enhanced Automated Builds.

+Enhanced Automated Build is displayed by default. You can switch to Classic Automated Build by clicking on this link at the top

+## Frequently asked questions
+
+1. I've previously linked my Github/Bitbucket account in the old Docker Hub. Do I need to re-link it?
+
+Unless you've linked your Github/Bitbucket account with the old Docker Cloud previously, you will need to [re-link](link-source.md) it
+with the new Docker Hub. 
+
+2. What happens to my old Docker Hub automated builds?
+
+They are now Classic Automated Builds. There are no functional difference with the old automated builds and everything 
+(build triggers, existing build rules etc) should continue to work seamlessly
+
+3. Is it possible to convert an existing Classic Automated Build into Enhanced Automated Build?
+
+This is currently unsupported. However, we are working to transition all builds into Enhanced Automated Build in
+the coming months.

 pushing to the registry. You can use these tests to create a continuous
 integration workflow where a build that fails its tests does not push the built
