Oracle 11i Sustaining Support

For those companies still on Oracle eBusiness Suite 11i, time is running out to make a move to Release 12.   Oracle gave companies a reprieve back at the Open World conference in October 2013 and adjusted their support model for 11.5.10.  The “Sustaining Support Exception” offering was introduced and provided a temporary service level which enabled customers to continue with their “Extended” support through December 2015.  With less than 20 months remaining, companies need to be making the move to R12 or calculating the risks associated with staying on “Sustaining” 11i support.

For companies contemplating remaining on the Sustaining Support option after December 2015, understanding what will be lost is key:

In summary, after December 2015 all 11.5.10 clients will be moved to the “Sustaining Support” level, offering access to the existing “Knowledge Base,” technical support, and the new releases, only – No fixes.

Here at TriCore we understand that some companies may continue to thrive for an extended time through the Sustaining support policy – These companies have typically made minimal updates to the environment, and are therefore comfortable living with any issues or problems that arise/ the risk of being on their own for production or security issues.


The concern for some companies, however, is that they have become accustomed to the stability and functionality of Oracle’s 11.5.10 Release.  The thought of paying to upgrade and the uncertainty of issues in the next release are keeping them from making the move, despite the opportunity the R12 upgrade presents to align the attention and focus of business and technology staff toward common goals.

When considering moving to a new Oracle release, several primary decisions and activities will determine the cost and effort for the transition.  The Upgrade versus Reimplementation option becomes the first directional question to be answered.   Oracle provides the “Upgrade” process as the standard approach for moving to a new release.  For 11.5.10 to R12 upgrade, Oracle has done a tremendous job with these upgrade scripts.  Our experience has been very positive with moving the data and implementing the new functionality with relative ease.

Re-implementation provides a second option for clients to move to the latest release.  Modifying your Chart of Accounts, General Ledger String structure, calendars or cost methods are the difficult configuration changes in Oracle EBS and the primary reason companies choose the more flexible Re-Implementation alternative. Replacing a heavily customized environment with new standard functionality or correcting data quality issues are two other common driving factors toward re-implementing over the upgrade process.

Regardless of the approach, companies looking to make the move can and should begin the process by evaluating a few options that will drive the effort and duration of the project.

By analyzing these areas, companies can develop the detailed plan to successfully move to Release 12. 

With a typical upgrade or re-implementation project taking six (6) to twelve (12) months, the remaining 20 months to “Sustaining” 11i support is quickly dwindling.  So as we teach our kids, a “No Decision” is actually a decision.  It’s important to make your 11i decisions informatively.
