8 Critical Steps to Master In Your E-Business Suite 12.2 Upgrade

You’ve made it to the final phase of your Oracle E-Business Suite 12.2 journey: Preparing for—and finally executing—the actual upgrade. The Continuous Innovation delivery model is finally within reach. 

In real-estate there’s a coined expression: “There are three things that matter in property: location, location, location.” When executing an upgrade, that expression should change to: “There are three things that matter in executing an upgrade: plan, plan, plan.” 

In other words, deploying a major upgrade like EBS 12.2 isn’t just as simple as flipping a switch. It starts with planning for the technical and functional changes the upgrade will have and mapping out the full multi-step process. 

Pre-Work: Determine what requirements you need to upgrade to EBS 12.2

Upgrading to the Oracle E-Business Suite 12.2 requires your database to be at the minimum version 11.2.0.4. If you haven’t upgraded to 11.2.0.4 or 12.1.0.2, you can upgrade your database prior to the upgrade downtime. In doing so, you’ll benefit from the latest security, performance, and stability updates—all while having one less step to perform when you upgrade to 12.2.

If you’re upgrading to 12.2 from 11.0 or 11i, your requirements look a little different. Your upgrade must be from 11.5.10.2. If your database isn’t operating at that level, you must first patch or upgrade to 11.5.10.2 and then to 12.2.

8 steps for successfully upgrading to EBS 12.2

Step 1: Prepare your database

You’ll need to upgrade your database to the minimum version or latest certified version. This might include: 

  • Migrating to a new platform.
  • Applying the latest database patches.

Step 2: Lay down the Oracle EBS 12.2 file system

Use the Rapid Install function to lay down the file system and technology stack. You’ll also want to apply the latest application tier technology stack patches. 

Step 3: Upgrade to 12.2.0

Next, you’ll apply the latest Oracle EBS pre-install patches, including the AD upgrade patch and EBS Consolidated Upgrade Patch.

Step 4: Enable online patching

After you apply the latest Online Patching Readiness Report Patch in this step, make sure you also apply the required updates to custom code and apply the enablement patch.

Step 5: Update to the latest code

This is where you’ll apply the latest EBS 12.2 Release Update Pack (RUP), complete post-upgrade steps, apply the latest security patches, and any other recommended patches. 

In this step, it’s important to note that you must apply the 12.2.3 or later RUP to your existing 12.2 system for production use. RUPs are cumulative and deliver error corrections and system updates for every other RUP that precedes it. That’s why Oracle recommends upgrading to the latest RUP available during your 12.2 upgrade.

Step 6: Deploy customizations, external integrations, and third-party integrations

The moment you’ve been waiting for—it’s time to ship it! 

Step 7: Perform advanced configuration

This step is optional for some. Here, you’ll carry out any of the advanced configurations needed in your 12.2 upgrade. This includes things like disaster recovery setup, reporting environment setup, or adding additional managed servers for scaling up. 

Step 8: Perform product-specific tasks

Your last and final step: Some of your products will include individual tasks that you’ll need to perform after the 12.2 upgrade is complete.
