You just need to use FTP connector + Transform module + Amazon S3 connector.
- Drag-and-drop these three nodes to Apatar work panel.
- Map them together. (FTP -> Transform -> S3)
- Configure FTP connector (enter the paths).
- Configure Amazon S3 connector (enter your Amazon AWS keys, etc.).
- Then open Transform module and link the fields.
- Run the transformation.
That's it.
