Oracle RAC 12c and Oracle RAC19c in the same Exadata X5
Is possible install Oracle RAC 12c (12.1.0.2) and Oracle RAC19c (19.X) in the same system Exadata X5?
To clarify the doubt, I have a production database with Oracle 12c installed in RAC with 2 nodes. The grid is already in version 19. I need to create a new database in RAC with 2 nodes in the same infrastructure but with version 19c.
