Can we directly upgrade Oracle 12.1 to 19 c or do we need to upgrade 12.1 to 12.2 first and then 19c, and when 19c will be available for download

    12CR2 is 18c is and 19c is - but short answer is 'yes' you can upgrade straight from 12cR1 to 19c. You'll want to consult the 19c upgrade guide when it's published. Here's the one for 18 - it should be VERY similar docs.oracle.com/en/database/oracle/oracle-database/18/upgrd/… Dec 21, 2018 at 15:46

The term used by Oracle is "direct upgrade". You have to take into consideration if your database is a multitenant (CDB) database.

From https://mikedietrichde.com/2018/12/14/premier-support-extension-for-oracle-19c-and-more/ :

Oracle, Oracle 18c and Oracle 19c all together sail under the cover of the “Oracle 12.2 Release Family” and hence have a common support frame

So direct upgrade should be available with the following versions:,,,,

I'm not adding the MOS support hyperlinks since if you are posting the question here I'm guessing you dont have a MOS account.
