(Hope I'm responding right, it has been such a long time)
Ensure that have a very good backup of everything, "just in case"!
I had just a RMAN backup on 5/2/2017, and went to upgrade Apex to the
newest version on my development server. That failed with the dreaded
ORA-600 errors, and I was unable to go go backwards, and support didn't
have me revert to the last backup, but instead kept me trying different
things to get past it.
Finally, after week, support said there was nothing they could do until I
either upgraded to the newest version of 12.1.xxxx or for me to upgrade to
the newest version of 12.2.xxxx. So I opted for the 12.2.xxx upgrade, and
that failed as well. Of course by then my RMAN backups had cycled out, so I
had no viable backups left.
Here it is now almost 4 months later and I have received one patch, which
seemed to fix some of the ORA-600 errors, but I still have a few remaining,
and a whole bunch of new errors I don't remember seeing before (but perhaps
that was because they were hidden amongst all of the ORA-600 errors).
This is on a Windows 2012 server, so if you are on a different platform,
perhaps you'll be okay. But for me in my case, my "Unbreakable Oracle" has
been broken for (2 days short of) 4 months. And as a disclaimer, I have
been doing DBA and programming work on Oracle since 1990, so I'm not a
simple newbie at this. :)
This link/document seems mainly to be in upgrading once you are already up
to version 12 and using the multi-tenant architecture, but it is a really
good article. https://community.oracle.com/docs/DOC-995765
Good luck!

Hi, Michael
In my opinion, *the* authority on Upgrading is Mike Dietrich: https://
mikedietrichde.com/
There is an (in)famous 555 page slide deck detailing all steps:
https://mikedietrichde.com/slides/
Have a look at his blog and slides - then after that you'll probably have
some more specific questions you can ask then ;-)
Happy upgrading :-)

can any one recommend a document that provide the steps. I will be using
data pump for the initial export/import and utilize Golden Gate to keep it
current before the switch over.
