When you import a pipeline, you can create a new pipeline or upgrade an existing one.
To import a pipeline:
Navigate to Management > Pipelines > Import.
Click Choose File and select the JSON file containing the pipeline.
If you want to upgrade an existing pipeline, select Upgrade Pipeline.
If the pipeline's name in the JSON file (not the name of the file itself) matches an existing pipeline, the pipeline's properties are updated with the new values, and new items, such as resources, are added. If the name of the pipeline is not found, the command has no effect.
Note: The pipeline's name is the first parameter in the JSON file.
