Identity IQ Workday Connector

Hi All,
We have a requirement to move the auth source from file feed to Workday and the client says they are using 38.1 version of Workday on their end and our IIQ version is 8.1p1. The Connector guide says that the supported version is 32.1(highest).
For now we are able to successfully place the connection and preview the data.
Are there any issues that we will foresee if we proceed with the integration?

Any inputs would be greatly helpful.

Thanks,
Harshitha
