Because of changes to Websphere Application Server architecture, it is not possible to perform a straight migration from Sametime 8.5.x (based on Websphere 7.0.0) to Sametime 9 (based on Websphere 8.5.5). Instead, you must deploy Sametime 9 separately from your 8.5.x deployment and then reproduce any custom configuration items the Sametime 9 deployment. A key area of concern is the migration of user based data stored in DB2 such as your Sametime Meeting Rooms, Chat Rooms and Broadcast communities. This article describes you can migrate that data.
