At Oracle OpenWorld this year (November 11-15, 2007, San Francisco, http://www.oracle.com/openworld/2007/index.html) there is a dedicated JD Edwards program self-contained in the San Francisco Hilton. This allows us to concentrated on JD Edwards specific topics, and gives us all a chance to interact together in a fairly small space.
Included in the JD Edwards program there will be a specific dedicated track for Upgrades with 5 sessions, and a second track for Migrations with 4 sessions. Each of these tracks will include a panel discussion with customers that have completed these projects, and a chance for you to ask them questions such as "how did you justify the project", "what did you learn to do and avoid", "where and when do you need consulting help", and more.
More information about the JD Edwards track itself is available here (http://www.oracle.com/openworld/2007/jd-edwards.html).
