    Hi daniels13ca,

     

    Seems no direct way available. But we can change the Power Query (M) code directly. One precondition is that the structure should be the same. If they have the same data type, that would be great. 

    1. Usually, the first two rows codes are the data source.

    2. If you have many queries, you have change them one by one. 

    3. Please pay attention to the two parts tagged by blue 1 and 2.

    4. Backup the code first, if you do anything wrong, you can paste the code back and do it again.

     

    If you have any problem doing it, please post the code here. Please mask the private parts first.

    Best Regards,

You would need to work on the Power Query section to ensure that the end tables match what you've had before.  Then in thorey it should work.

 

I have heard a tail that sometimes even when everthing is 100% the same the visiuals need to be rebuilt, I take this with a pinch of salt however.

 

in sure that you have the data tables correct with the correct data types and you should be good to go.
