Okta Identity Engine upgrade - Will Okta Classic APIs work on Okta Identity Engine (OIE)?
The FAQs (https://support.okta.com/help/s/article/FAQs-about-the-Okta-Identity-Engine-upgrade?language=en_US) say:
"All of the legacy APIs will continue to work on Okta Classic."
Does that mean that all of the legacy APIs will continue to work on Okta Identity Engine also?

If the feature exists in both its leveraging the same API endpoint with the same calls. If the feature exists in classic and not OIE then the call won't work in OIE and vice versa.
A good example of this is "Devices" which doesn't have classic functionality. The API documentation indicates its specifically for OIE only:
