We've been developing reports in a dev environment for a few months and we're ready for a data migration and to point these reports to a new location.
What I need to do is change the data source for all of these reports without having to go to each report, change the data source, and re-deploy the reports.
I'm thinking I could be able to just change the current data source from the SSRS portal to point to the new location, but I would still need to touch each report and update them in source control.
I also came across a page for the RS.exe utility here. Not sure if that is going to do what I'm looking for.
Is there a best practice for this or is touching each report the only way to accomplish what I'm looking for?
