Just to chime in about that cop file, if all you want is to free up space, you definitely want to try deleting CDR, CMR and traces in first place, if you're planning to upgrade, that cop file will take away the chance to rollback to the previous version if something happens.
I know its been a while, but am faced with a situation of upgrading from 9.1.x to 12.5.x. I applied the RSA cop and got the uprade running till i got the not enough space errors, consider cleaning up space, Function: validate_free_space(), Not enough etc..
I had the common_free_space cop i used 3 years back luckily so i got to PCD and run that cop upgrade. Runs and all but its taken a minute. its been close to two hours and its still running. Just wondering if it has stalled or something got stuck. CLI upgrade status returns being configured.
Is there a way to check whats really going on and determine if the process got stuck?
