# Blue/Green deployment using Manifest

Blue/green strategy is a deployment strategy that is designed to minimize risk by gradually copying the contents of the old server group onto the new before disabling the old server group. 

Using a Blue/Green (AKA a red/black) Deployment strategy is easy, as Spinnaker natively supports a Blue/green strategy.

To use a Blue green Strategy,

1. **Go to** [**Application Dashboard**](https://docs.opsmx.com/user-guide/dashboard/application-dashboard): When you log in to ISD the application dashboard is displayed with the list of applications. You can create a new application also as given in [**create a new application**](https://docs.opsmx.com/release-history/previous-releases/isd-4.0/knowledge-base/manage-application/create-an-application). 
2. Click on the application for which you want to build this pipeline.
