There is no button to transfer ownership, but I certainly wish there was. I think it's not quite as terrible as it seems. A suggestion is to download the app from the exchange called the YAML converter.
In your because you were simply changing the ownership and not any of the table references, all you need to do is to change the setting for the setting lovingly called the "Slug".
So you should be able to use the YAML converter to change the slug simply just copy paste to your clipboard and import the new pipeline.
I have not used that in a long time so feel free to post back with your success or obstacle
