New Upgrade Features
Upgrades: Releases 7.0.x, 7.5.x, 7.7.x. Environments: All environments. Release 7.7
The following upgrade features were introduced at Release 7.7.
- Incorporate Custom Layouts (ICL). This feature enables you to preserve the UI look and feel of your currently installed release during the repository merge, reducing the workload required to reconfigure customizations after the upgrade. ICL is available for Siebel 7.x upgrades only; however, it is included in Release 7.7.2 and later. For more information, see About the Incorporate Custom Layout (ICL) Upgrade Option.
- Production Upgrade Tuner. This utility analyzes the SQL commands used to upgrade the development environment. It then helps you eliminate unneeded SQL commands and perform other operations intended to improve the performance of the production environment upgrade. For more information, see About Tuning the Production Upgrade Scripts.
