How to import frcProcesses with StateCode "Approved"?

Summary:

Dear all,

We need to import a number of frcProcesses from a previous system setting the StateCode as "Approved".

It seems that from "Data Migration", the "StateCode" field is not available, and it is not updatable via REST either.

Is it possible to update these values in any other way rather than open each record and press submit? That could be an import or a REST/SOAP call or any other option/workaround.

Thanks.

We need to import a number of frcProcesses from a previous system, setting the StateCode as "Approved" by default. We would like to avoid to enter each record and manually click "Submit". We need this to preserve data and also because for a number of imported processes, users have to still reply to some questions, so we want to use the batch assessment functionality but we cannot do so if the processes are not "Approved".
