EBS -- Upgrading EBS 12.1.3 to 12.2 -- the general steps

In this blog post, I want to give you a list which includes the general steps that can be included in the project plan of an EBS 12.1.3 to 12.2 upgrade project.

By taking the following phases and the related steps into account, you may calculate your effort and do your project plan accordingly.

I wanted to use EBS 12.1.3 as the source version because it is a very common version in EBS customer environments. While giving the steps, I also wanted to highlight the teams responsible for completing those steps. (apps DBA team, Functional team, core business users etc..).

Of course, some of these steps like the "upgrade database step" is optional .( if your db release is up-to-date enough.)

Phase 1      

• Upgrade the database on the existing EBS 12.1: apps DBA team      
• Execute a functional test: EBS functional team

Phase 2      

• Install all application pre-upgrade patches: apps DBA team      
• Verify the instance: EBS functional team

Phase 3      

• Execute all functional pre-upgrade tasks including customizations: functional team      
• Perform a full system backup: System and apps DBA team   

 Phase 4
