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'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

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.
