Split Pipeline-Builder pipeline into two new pipelines

Context: I have a Pipeline Builder pipeline, with two fully independent paths. To enable a partial migration to lightweight transforms, I want to split the pipeline into two pipelines. The output datasets are used by a larger set of transforms, because of that I would love to maintain the same outputs.

Question: What is the best approach to spilt a builder pipeline and main the same output datasets?

Great that you want to migrate to lightweight!

I would copy and paste one of the paths into a separate pipeline builder file, and then you should be able to choose to overwrite the original output before you deploy (see screenshot below). Make sure what you move over is also deleted from the original pipeline.
