Hi @Leonardo clemente ,
Welcome to Microsoft Q&A Platform. Thanks for posting the query.
One easy approach I can think of is to use GIT configuration in the pipeline you want to copy and publishing to a branch. In the new data factory, you can import from the same branch by setting up GIT configuration. Please find documentation related to it. And automated process when moving across environments is implemented using Azure DevOps.
Hope this helps! Please let us know if requirement is different or for further queries and we will be happy to assist.
