Enterprise Manager (EM) clean up in Oracle Database 11.2-12.2 is targeting Enterprise Manager Database Control only. EM DB Control does not exist anymore since Oracle Database 12c and got replaced by EM Express, a light-weight EM.
I’m not a Cloud Control expert but I use the tool from time to time – and most of my customers are heavy users of it, especially in larger deployments.
If you use Oracle Enterprise Manager Cloud Control 12c (220.127.116.11, 18.104.22.168 or 22.214.171.124) and would like to evaluate your options to upgrade to Oracle Enterprise Manager Cloud Control 13c then please consult the following very useful documentation:

Just be aware:
As of July 15, 2016 I received several emails and comments by customers about issues with the migration to OEM 13c, e.g.:
- bug 23017970 – – 12c-13c upg failed at repos config “invalid LOB locator specified: ORA-22275”
- bug 23542135 – OMS Upgrade failed during plugin pre-req
