"ORA-20000: Direct downgrade of EM Database Control not supported"
This is a known issue and documented in <Document 443890.1>. As a resolution of this issue, one need to execute below step and then do the downgrade
DROP USER sysman CASCADE;
Even after running the above step, same error is received again and again.
Once a SYSMAN user is dropped successfully and if tried again the user should get a message 'SYSMAN' does not exist. But in this case, the message "SYSMAN is dropped" keeps appearing all the time.
