I'm upgrading an existing RAC database from 10.2.0.3 to 188.8.131.52 on new hardware. I have issue where I am trying to add the new database to EM 12c and its giving me an error that the individual rac names are already registered. Yes they are. On different hosts. I have a unquie name defined the cluster and that works fine. Its just when it goes to add the individual targets... they fails with name already exists.
Anyone know how to work around this?
