Promoting a preparation across environments
The best practice when using Talend Data Preparation is to set up one instance for each environment of your production chain.
Talend only supports promoting a preparation between identical product versions.
To promote a preparation from one environment to the other, you have to export it from the source environment, and then import it back to your target environment.
For the import to work, a dataset with the same name and schema as the one which the export was based on must exist on the target environment.
Let's take the example of a simple preparation, used to remove invalid values and formatting errors from an Excel file containing customers data. This preparation is saved as customers preparation.
The following procedure will detail how to export this simple preparation into a file that can be reimported to a new environment.
