11g to 12c migration gotchas

edited Apr 5, 2018 5:03AM in Database Install/Upgrade/Opatch (MOSC) 2 commentsAnswered

I am embarking on an 11g to 12c Oracle DB migration. I will need to do it at least twice, once for testing, a 2nd time fro production. My initial thought is to use expdp/impdp. I export "full" the DB nightly using expdp.

My problem in the past when importing a full DB is it can get squirrely regarding the system schema/users. A full import tries to muck with system schemas (sys, system, sysman...). My new 12c DB is a portable DB, and obviously I want none of the settings or data from the system schemas, that may hose my new DB.
