Issues to Consider Before Upgrading

Depending upon whether you are migrating from client/server or character mode, you may need to consider one or more of the following issues prior to upgrading your applications:
- Defining UI standards: If you are migrating from character-mode deployment, you should sonsider the appearance of the user interface, which now can be enhanced with different colors and fonts. you may want to define standards for the look and feel of the application.
- Upgrading referenced forms, menus, libraries, and object libraries: If your application contains objects that are referenced from other modules, be sure to upgrade the referenced modules first. you also must first upgrade attached PL/SQL libraries and menus used by a form prior to upgrading that form.
- Defining navigation: In character-mode applications, users navigate mainly by using the eyboard. On the Web, users are no longer restricted to keyboard navigation, so you may need to redefine the logic of the application. For example, validation should be attached to the item rather than to the attempt to navigate to the next item.
- Sharing code and objects: You should consider ways to promote similarities among objets. Because only UI differences are transmitted over the network, fewer differences among objects reduces network traffic. Using Object Groups, Property Classes, and Object Libraries with SmartClasses helps to accomplilsh this. You can also share libraries among Forms modules to reduce memory requirements.
- Recoding triggers: If your forms contain any V2-style triggers, you must recode them in PL/SQL prior to the upgrade. V2-style triggers are dropped when you upgrade to Oracle Forms 10g.
