OUD 12c integration with OIM 12c

Question

I want to fetch all the users from OUD 12c to OIM 12c. Although I could do that when the OUD 12c was setup with the database but now the OUD installed on my machine does not have a database/RCU configuration. So now I am not able to fetch the users. Can anyone please help me with this. These were the steps I followed to integrate OUD and OIM -

1. Install OID connector
2. Create target and authoritative applications
3. Run the jobs in the scheduler

Am I missing any steps? Please help. Thank you :)
