Spend some time to understand E-Business Suite Releases – Support Policies. I am referring to (Doc ID 1494891.1). In this most of your questions are answered. Like E-Business Suite General Support Policy Information,

  • Why is Oracle providing Sustaining Support Exception for EBS 11.5.10?
  • Will customers need to purchase an additional contract for the 11.5.10 Exception to Sustaining Support?
  • What defines Severity 1 Production Support in the 11.5.10 Exception to Sustaining Support?
  • What are the terms and conditions for the Critical Patch Updates (CPUs) during the exception period for 11i?
  • What are the differences in the Lifetime Support Policy feature benefits from Extended Support to the Severity 1 Production Support in the 11.5.10 Exception to Sustaining Support?
  • What happens to open non-severity 1 bugs once 11.5.10 enters Sustaining Support?
  • Which EBS release version does Oracle recommend customers upgrade to from 11.5.10?

Hope you enjoy reading valuable MOS notes.
