Earlier, when you upgraded to a new version of CA ERwin DM, only the schema was upgraded. To upgrade your models, you opened each model in the new version. This process took much of your time, especially when you had to upgrade large models. From CA ERwin DM Version 9.0, upgrading models is automated through the Mart Upgrade utility. The utility lets you upgrade not just models, but users, profiles, and permissions too. In addition, the utility also lets you upgrade to a different database.
If your source Mart version is release 7.0 through 7.3.12, the upgrade happens in two stages. First, the Mart is upgraded to CA ERwin DM version 8.0 and then it is upgraded to version 9.1. The existing upgrade process is used to upgrade from a lower version to 8.0. After the source Mart is brought up to version 8.0, the new Upgrade Mart utility is used to upgrade to version 9.1. In the new Upgrade Mart utility, you must select the models that you want to upgrade.
Note: The Upgrade Mart utility is available only if you install it while installing CA ERwin DM Version 9.1.
The Upgrade Mart utility lets you upgrade models in several ways. You can choose the best way that helps you get started with your work quickly. Upgrade models in one of the following ways:
Regardless of the option you select, you can start working on a model after the model is upgraded. You do not need to wait until all the models are upgraded.
