Move my visualization to another data source

Hi all 

I have a big old report that contains a dozen of tabs and hundreds of visuals 

I am currently working on building a new data source with different table and column names. 

I want to keep the same user interface and visuals and connect everything to the new data source. 

The visuals will collapse, but it's okay, I will reconnect everything manually.   

Is there a best practice for doing this?
