I did an in place SQL server reporting server upgrade for 2017 SSRS.
The server has both database engine and SSRS service.
The SSRS service is the newest download from website.
I can see from reporting server configuration manager it is the standard edition and the product version is 14.0.600.594.
But some of the datasource we created before not working.
The oracle type for the connection, there is a line under it saying The data extension used here is not available. It has either been uninstalled, or it is not configured correctly.
What could be wrong?
