Problem when changing server from test to production environment

Hi,

I've got a report that is connected a tabular model running on my test analysis services server (ASTEST).  I want to change the datasource so that the report is connected to the same model on my production server (ASPROD).  When I change the server, all of my visualizations break with the message "Can't display the visual.  See details"

Here are the steps I took to change the data source:

1. Edit Queries
2. Data source settings
3. Change server name and specify model name
4. Select the correct perspective from my model

I know my model on ASPROD is good and be accessed by PBIDesktop since I created a new report and pointed it to that model with no issues.

Any ideas on how to resolve this?  I really don't want to have to recreate this report just because the datasource name has changed.

Thanks!
