Introduction
You can migrate existing report definitions from oracle developer release1 (Reports 2.5) and oracle developer release 2(Reports 3.0) by opening and saving the report in the oracle developer release 6.0 Report Builder.
Upgrading PL/SQL Code
Because of syntax differences between the PL/SQL versions, an upgrade utility automatically verifies your PL/SQL syntax when you first open an older report definition.
The upgrade utility reports any syntax incompatibilities that it cannot correct, and creates a log file for you to view the messages and manually alter the code as necessary.
Modifying migrated reports
You can reenter the wizard to make changes to an upgraded report, but remember that the wizard recreates your layout, so you lose all layout changes, including layout triggers, that existed in the original report definition.
To make individual changes to upgraded report, use the layout model editor, which also provides an additional default layout tool.
Migrating printer definition files
The older oracle developer printer definition files (.prt), used for character-mode reports only, are totally compatible with Oracle Reports Release 6.0. Copy your customized printer definition files to the printer directory
<oracle_home>\report6 0\printers
