# Replacing your dataset
<a name="replacing-your-dataset"></a>

Replacing your dataset allows you to change the data without re-creating the project from the beginning.

You may want to do this after [reviewing the ingestion of your dataset](understanding-ingestion-validation.md), and addressing problems with the job, files, or sensors.

**Note**  
If you want to change your schema, then you must start over with a new project.

The **Replace dataset** page is similar to the **Ingest dataset** page that you visited earlier in the workflow. The main difference is that the **Replace dataset** page does not ask you for information about how you named your .csv files. When you replace a dataset, Lookout for Equipment re-uses the schema detection information that you entered before.

To replace your dataset:
+ From the **Dataset details** screen, choose **Replace dataset**. 
+ On the **Replace dataset** page, indicate the location of your data on Amazon S3 and choose your IAM role.
+ Choose **Start ingestion**.

After the procedure above, you'll [review your dataset ingestion](understanding-ingestion-validation.md) once again.
