    1. Select Manage > Environments
    2. select your DataGuard environment, then Discover the CDB where your PDB dSource is in.

After you have plugged your PDB dSource into the new CDB, discover that host environment that has the new CDB into Delphix, if it is not already discovered. Discover the new CDB from the Delphix Management application,:
    1. Select Manage > Environments
    2. select your new CDB environment, then Discover the new CDB where your PDB dSource is in.
