Sometimes, you'll want to re-use the existing components of a Blueprint with only a few slight changes. In these cases, duplication will allow you to avoid the hassle of manually repeating an existing configuration.
Here's the steps you'll need to take to duplicate a Blueprint:
Select the name of the Blueprint that you want to duplicate, or click the edit button.
Select the duplicate button in the bottom-right hand corner.
At this point, your Blueprint has been successfully duplicated with a name that indicates the Blueprint it was originally a copy of. However, we recommend making a few adjustments.
Decide on a new Blueprint name.
Set your Blueprint's state to Active.
Save your newly Duplicated Blueprint.
The Duplication reference article details out exactly what happens when you press the duplication button.
