I am part of data replication team, recently we have upgrade JDE XE to 9.1 . Oracle has provide a tool to migrate the data from XE to E1 automatically as part of upgradation. But there are already user defined View which is using existing table structure. But after upgradation we see there is change in the table structure, columns either deleted or newly column added. Is there any way to understand how the data column are link or mapped to the new version.
Also is there any document which help to understand data conversion statergy.
