I just completed an upgrade to 13c on OL7. But I didn't do an upgrade at all. Our hardware was very old, so I did a new install and ran 12c and 13c agents at the same time. Once I was sure I had everything working in 13c, I shutdown 12c and decommissioned it.

I have Oracle enterprise manager cloud control 12 c release 4 running on Linux 5 box and management would like to migrate this to linux 6 and Oracle Enterprice manager cloud control 13 at the same time. Anybody ever do this? Is there a way to do this in one step? Any thoughts on the best way to accomplish this would be appreciated. Of course management wants very little down time.

I'm part way through a similar migration right now. My EM 12.1.0.5.0 OMS is on OL5. The 11.2.0.3 repository DB was on the same server, but I've upgraded it to 12.1, then migrated to an OL7 box that may someday also host the EM13cR2 OMS. But that move requires an intermediate OL6 box, as EM12c won't work on OL7 and EM13cR2 won't work on OL5.

A good place to start for your migration is http://docs.oracle.com/cd/E24628_01/install.121/e24089/ha_backup_recover.htm#EMADV10748 to move the Repository (if needed) and http://docs.oracle.com/cd/E24628_01/install.121/e24089/ha_backup_recover.htm#EMADV10754 to move the OMS. However, there's some confusion in those docs so I opened an SR with Oracle Support anyway.

FWIW, from recent posts here about usability issues with EM13c, I've suspended my upgrade for now. Check out the list archives for August at https://www.freelists.org/archive/oracle-l/08-2017. Also, search the older archives at https://www.freelists.org/archive/oracle-l for "OMS move" (sans quotes). oracle-l Mailing List Archive - Oracle Freelists<https://www.freelists.org/archive/oracle-l> www.freelists.org

I'm not sure why this task needs to be so complex, but it is. Take your time, plan it out, and test if you can.

GL!
