You may not be able to incorporate entire IDQ rules into IICS-CDI (Cloud Data Integration). You may try IICS - CDQ (Cloud Data Quality) and recently two DQ transformations are added into CDI as well (Cleanse and Verifier). So if your requirement needs just these transformations, it may be possible or else you need to check IICS - CDQ.
Note: I don't have hands-on experience on IDQ. The above information is based on documentation. So please verify!
