Install Importer from the Marketplace (beta channel) on the site you're importing into. In ACP > Modules > Tools > Importer > Global Config:
| Setting | What it does |
|---|---|
| Source Site | The full address of the site with the Exporter and its JSON files, such as https://oldsite.com. Needed even when it's this site. |
| Site Access Key | The same key as the Exporter's Site Access Key |
| Queue Items | Imports items in the background, through the queue, instead of at once (default: off). Members are always imported at once. |
Save. Import JSON Files then lists the files on the source site.
