EBS Upgrade Part 9 - 11.5.9 Database 9i RHEL 4 to EBS 12.2 Database 19c OEL 7
Now the current state of the EBS and DB is 12.1.3 / 11.2.0.4 running on OEL6. Well to get to EBS 12.2 Database 19c there are two ways.
- The best way is to keep 11.2.0.4 database and upgrade EBS 12.1.3 to EBS 12.2. This is stable and kind of been done for some years now.
- The recent supported way is to get the database upgrade to 19c multi-tenant architecture on EBS 12.1.3 and then run upgrade EBS to 12.2
Well the second is being certified but not many customers have gone through this in 2020. So I would suggest to choose option 1. But what if you are in EBS 12.1.3 and you have upgraded your database to 19c. You have to go through option 2.
So I have decided to go by Option 2 to see what is the complication.
Here are the steps involved to upgrade to 19c
- Pre - Database Upgrade From 11.2.0.4 to 19c (19.3)
- Database Installaion 19c (19.3)
- Database Upgrade19c (19.3)
- Post Database Upgrade19c (19.3)
- Convert Database to Multitenant Architecture
