In the single cloud tenant, we can setup development, staging and production environment and use a different data source(connection string) for each environment. Please refer to the below steps,
For all your existing datasets, change the data source and clone for use in different environments. Consider you have a dataset named “Employee_Dev” used for the development environment.
Repeat the process for all your available datasets.
Follow the same procedure to create dataset with a production connection string.
For all your development reports, change the dataset and copy to the staging category.
Hence, the staging report will now render with the staging connection string. Repeat the process for all of your reports.
Follow the same procedure to copy the report to the production category with the corresponding dataset.
