Hi all,
Please i'm missing something when it comes to upgrading from Oracle 11g to Oracle 12c.
I'm using this article for my upgrade (https://oracle-base.com/articles/12c/upgrading-to-12c)
Presently i have oracle 11g installed and im asked to use DBUA to upgrade. My question is am i to install Oracle 12c first and then run 12c DBUA? if so, then what will be new ORACLE_HOME and ORACLE_BASE directory? because there seem to be a conflict with the previously installed Oracle 11g when installing Oracle 12c.
Thanks.
