You can duplicate any deployed pipeline. This creates an in-memory copy of the pipeline appending _<v1, v2, v3> copy to the name when opens it within in the Pipeline Studio.
At this point, you can rename the pipeline to a unique name and then either save it as a draft or deploy it as a new pipeline. All new pipelines need a unique name. A common practice is to increment the names, from Demo-1 to Demo-2 with each new duplicate pipeline.
