This year will be time for migration from an on-premise customer environment to the Cloud which is not a very easy task with all unknown complexity compare to on-premise.

My recommendation: if you have the plan to migrate the application to Kubernetes architecture first to migrate your on-premise environment to the Cloud in order to discover all specifics, what is supported and what is not supported from infrastructure, Application, Database etc.

You can check also the following blog for WebLogic 12.2 and Database 19c support matrix - http://dirknachbar.blogspot.com/2019/06/oracle-19c-certified-for-oracle-fusion.html

What is the scope of this post:

- Create a free Oracle account in order to create all infrastructure - this will be available soon 

- Export current standard edition database  - this will be available soon 

- Create a new ATP database - current post

- Import dump file to ATP database and fix all objects issues  - this will be available soon 

- Create VM instance Linux 7.7  - Here

- Setup ssh configuration in order to be able to export X11 Display  - Here

Create Autonomous Database

Select Compartment, add Display name, Database name, select workload type -> Transaction Processing, Chose a deployment type  - Shared infrastructure ( in case of free tear ) or dedicated infrastructure 

Select Aways free if you consider using such an approach, also add a password for Admin user ( privilege user like SYSDBA, DBA but not exactly )

Now select access control rule e.g. - check your IP and add it as values, keep in mind that you can add more than one IP

Also, select License included and click on -> Create Autonomous Database 

We have to wait a few sec/min until your label of ATP shift from Orange to Green :)

Once ATP database has been provisioned, you can click on DB Connection and download Wallet or copy connection string 

Here you have to enter a strong password for Admin user
