Oracle has postponed End of Support for 11.2.0.4 many, many times, but no mas! In fact, if you're running EBS, 11.2.0.4 is STILL supported with extended support fees waived, almost 11 years after its initial release. I know a couple of large EBS shops that are still running on 11.2.0.4. To upgrade the database for EBS is a huge task...so its understandable why they'd put this off as long as possible...but time is running out. See 742060.1 for details.
Also, 12.1 premier support ran out almost a year ago, but I know there are a lot of people still running critical databases on that version.
At this point, everybody is aware that Oracle changed their naming convention...so you can think of 19.3 really being 12.2.X. There are *many* great new features in 19.3...its the terminal release of Oracle 12.2. Oracle recommends you not upgrade at this point to anything other that 19c. I've heard rumors that the next db version that'll be supported for EBS is 19.3 (currently the max is 12.1...they're skipping 12.2 and 18.3.)
So its inevitable...you're going to go to 19c. Here's are some things to keep in mind:
1. In order to upgrade your database to 19.3, you...of course...need to upgrade your ASM's Grid Infrastructure to 19.3
2. In order to upgrade your Grid Infrastructure to 19.3, (assuming you're on RHEL) you MUST be on RHEL 7. 18.X was fine with RHEL 6, but 19.3 requires RHEL 7.
3. There are a lot of changes in the OS requirements. Make sure you review/verify the install documentation before you install it.
I'll post more about the changes in the 19.3 upgrade process later.
