Hi Community Members,
Just like previously with Oracle 18c, I had the chance to test the Upgrade to 19c as well
The environment I was using is basically the same as before:
Source Oracle RDBMS Release: 18
A CDB with 2 PDBs (ABAP and JAVA in separate PDBs)
SAP NW 7.5
This time the upgrade was even smoother and run better. With the experience gathered through 18c Upgrade, performing this taks was a little more easier then before, However I cam accros certain challenges.
The most intriguing part is that dbac_install and dbac_drop scripts are still not adjusted to the Multitenant environment. We are definitely working on this one to get this resolved.
SAP notes that will contain more information (once they get released):

In addition to these, I released the Upgrade Guide here.
