User, Role, and Organization UDFs Missing After Upgrade from 11g to 12.2.1.x

The User Defined Fields (UDFs) previously defined in the organization.xml and user.xml files are missing in the MDS storage, after the upgrade of Oracle Identity Manager from 11g (11.1.2.3) to 12c (12.2.1.x).
To resolve this issue:
  1. Export the required files from the MDS storage.
    • /db/identity/entity-definition/Organization.xml (for Organization UDFs)
    • /db/identity/entity-definition/Role.xml (for Roles UDFs)
    • /file/user.xml (for Users UDFs)
  2. Append the missing UDFs and save the changes.
  3. Import the modified files to MDS.
