EM 13c – How to Upgrade from EM Cloud Control 12c

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 (, or and would like to evaluate your options to upgrade to Oracle Enterprise Manager Cloud Control 13c then please consult the following very useful documentation:

If you are searching for the software please find it here:

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.:

So please check with Oracle Support first – and test the migration before doing it on a actual life system.

  1. Tried upgrade but hit the bug:

    Bug 23017970 : 12c-13c upg failed at repos config "invalid LOB locator specified: ORA-22275"

    Had to rollback to since there is no resolution to the bug.

  2. Hello Mike, I am Facundo from Argentina.

    I would like to add, that exists a new Note: EM 13c: Checklist for Upgrading Enterprise Manager Cloud Control from Version to 13.2 (Doc ID 2199855.1).


  3. Hello Mike,

    I have an EM12c running OMS and repository on one machine with windows 2008 R2.
    I want to upgrade to version 13.2 with separate machines for repository and OMS. Both on new server running windows 2012R2.
    To bring the repository to the new server, I would use datapump.
    But how can I upgrade / configure the OMS on a new machine.
    Is there a way to do this?
    Can you provide a step by step guide?

    Kind regards,
    Korinna Kurrer

    • Korinna,

      you can’t expdp/impdp the OEM repository database. It’s one of the most complex things ever build within an Oracle database.
      You’ll have to copy the database over.

      As far as I understand the procedure:
      Shutdown the repository database with shutdown immediate.
      Then copy it over to the new server.
      Start it up (which includes creating the services necessary on Windows).
      Then install the new OEM software – and I silently hope/assume that you can tell the install where your repository is located at.

      In case this is not the case you may please open an SR unless you can’t find a guideline in the documentation or on MOS.
