You can still use Oracle and third-party consulting services

Implementation, post-go-live, and upgrade services are available through Oracle Life Sciences Consulting (LSC) and Oracle Partner Network (OPN) consultants.

If you are working with Oracle Life Sciences Consulting (LSC), when you go live with Oracle Argus Cloud Service, HSC hands over the support responsibility to a CSDM. If you're working with a third-party consulting service, they will call upon CSDM as needed.
