Plan Your Migration From Data Modeler to Semantic Modeler
Use this information to understand the steps required to migrate your semantic model from Data Modeler to Semantic Modeler.
Note:
Data Modeler is desupported in the current (May 2024) Oracle Analytics release. For now you can access Data Modeler with a bookmarked URL. However, the bookmarked URL option won't be available starting in the July 2024 release. Oracle strongly recommends that you migrate now to avoid any interruptions in the development or upkeep of your semantic model.
| Step | Description |
|---|---|
| Check the model's data source |
Confirm that the model you want to migrate uses a data source that Semantic Modeler supports. Semantic Modeler only supports relational data sources. Be sure to remove or replace any unsupported data sources in the semantic model before migration. |
| Go to your Oracle Analytics development or test environment |
Perform the semantic model migration in a non-production environment, such as an existing development or test environment, before making changes to your production environment. |
| Back up your environment |
Use the Console to take a full snapshot of your development or test environment. You can use the snapshot to restore the environment if you discover issues after deploying the imported model. See Take a Snapshot. |
| Import the model |
In Semantic Modeler, create a new model and then import the deployed model from Data Modeler into the new model. |
| Modify the imported model |
Use Semantic Modeler to modify the imported model, and to learn about and try Semantic Modeler's many features. After import, you're working with a copy of the data model in Semantic Modeler. As long as you don't deploy the model from Semantic Modeler, you can still access and work on the model in Data Modeler. If you updated the model in Data Modeler and want to move the changes to Semantic Modeler, then you need to import the model again. |
| Deploy the model |
If the model is working as expected and passes advanced consistency check, then deploy the model from Semantic Modeler. When you deploy the model, Oracle Analytics disables your access to Data Modeler and you can no longer use it to develop or modify the semantic model. See Deploy a Semantic Model and Check the Consistency of a Semantic Model. |
| Revert to Data Modeler if necessary |
If you deployed the model from Semantic Modeler and discover issues such as visualizations not displaying the correct data, then use the Console to restore your environment to the state when the snapshot was taken. If you revert your environment, any changes you made on your environment since you took the snapshot are lost. |
