Just replace your data sources in the desktop and then publish them into server

We don't have a feature yet to change data sources for a workbook within Tableau Online. As Shasank said, you can do this with Desktop. Some things you can do with data sources are: create a new workbook from a data source, edit the workbook, and make changes to the data source (schedule, credentials, permissions, etc). However I don't think these address your need.
Thank you for your feedback and I'll relay it to the product team.
