The Oracle Application Users Group's (OAUG’s) Upgrade Special Interest Group (Upgrade SIG) focuses on issues relating to upgrading Oracle E-Business Applications Release 11i and Release 12. These issues include Release 11i Mandatory Baseline Patching requirements, technology stack requirements, performance techniques, various upgrade tools, specific platform related information as well as current Oracle announcements on de-support and availability issues. We also cover the 12.1.3 and 12.2.X releases and provide insight as well as experience around what 12.2 on-line patching will mean to adopters. The group provides a special problem-solving forum for those involved in the complexity of upgrading their applications. The Upgrade SIG meets bi-annually at the OAUG Collaborate and Oracle OpenWorld conferences and sponsors Expert panels at those events.
