Task flow to move across deployment pipeline

Hi, abpgupta 

I am glad to help you.

First you need to make sure you have enough permissions to move task flows across environments.

Power BI provides a deployment pipeline feature that helps you move content between workspaces. You can create a task flow in the development workspace and then use the deployment pipeline to move it to the test workspace.

These are the official documents on the subject and I hope you find them helpful:

Power BI implementation planning: Deploy content - Power BI | Microsoft Learn

The Microsoft Fabric deployment pipelines process - Microsoft Fabric | Microsoft Learn

I hope my suggestions give you good ideas, if you have any more questions, please clarify in a follow-up reply.
Best Regards,
Fen Ling,

Please let me know if it's not possible to move Task diagram to next stage workspace. Thanks! 

I share this question. It is clear how to transfer Items between stages, but how do I design a workflow in "Dev," tinker with it, then "push" it to "Test" and eventually "Prod" when I want?
