API for ONTAP 8 vs ONTAP 9

guenterw — Wed, 04 Jun 2025 15:07:56 GMT

We have a StaaS project underway to automate volume creation/deletion. It is developed on top of the API for ONTAP 8. We want to know if the ONTAP 9 API is compatible with the ONTAP 8 API for purposes of regression testing?

Is it possible to down grade back to ONTAP 8 in case we need to?

You can download the Ontap-9 API documentation (ontapi_1.100) from Here.

Once you download the "Reference Manual for ONTAP 9.0 APIs" I suggest to use a webserver to navigate easily.

There you can see the "What is new" link. that will help you to understand the whats been added, changed or deprecated in OnTap 9 API.

Hope this help..
