6. In the Use Template panel, click Upload Local File to upload the downloaded TXT file.

Usage notes
You can follow the procedure in this topic to migrate an application schema between applications across regions, between applications of different specifications, or between applications of different types.
If the source application does not have a data source, you can follow the procedure in this topic only to migrate the application schema to the destination application. You need to re-import the data in the source application to the destination application by calling API operations.
If the source application has a data source, the downloaded template does not contain database information by default. You need to manually configure the database information for the destination application after you upload the template.
