Siebel Database Upgrade Guide > Upgrading to eConfigurator Version 7 > Approach 2: Modifying Your Existing Implementation >

Overview

To manually reimplement your models, you need to first understand the new Siebel 7 features. Then you should analyze your Release 6.x models and determine what kind of data can be carried over and what can be reimplemented by using the new features. Because Approach 1: Using the Standard Upgrade Tool describes the procedures that make use of most of your Release 6.x model data, it is reasonable to assume that if you choose to follow Approach 2, you will want to revamp most of your product definitions to make full use of the new features. The sections that follow outline a set of suggested processes for you to plan and implement your new Siebel 7 configuration environment.

NOTE:  The new models you created in the Siebel 7 environment are generally not usable in reading your upgraded quotes.
