# 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.  **Create a new Pipeline**: Create a new pipeline by clicking on the pipelines tab and clicking on the create button in the spinnaker.
