When using the Deploy API it is possible to transport a package from an App to its Environments. But is there also a possibility to transport a package from App A to an Environment in App B using the Mendix API?
After issuing a support ticket at Mendix, I received the following answer:
Thank you for your information. Unfortunately it's not possible to transport an deployment package from Application A to Application B without uploading the file twice.
Hopefully it will be implemented in a feature release.
