The stix2-elevator is a python script written to automatically convert STIX 1.x content to STIX 2.x. It is available at https://github.com/oasis-open/cti-stix-elevator/.

It important to emphasize that the elevator is not for use in a production system without human inspection of the results it produces. It is more a tool to explore the differences between STIX 2.x and STIX 1.x content previously created.

While much of the conversion is straightforward, several assumptions concerning the meaning of the STIX 1.x needed to be made. These are discussed in ​Conversion Issues section.

The elevator produces many messages during the conversion process, that can be reviewed manually to help enhance the automatically produced content, in order to reflect the original content more accurately. A list of these messages can be found in Warning Messages section.
