# Rename Columns

The migration requires the target table (if it already exists) to have the same schema as the source table. For convenience, it is possible to rename some item columns along the way.

Indicate in the migration configuration which columns to rename with the `renames` top-level property. For instance, to rename the column `foo` into `bar`, and `xxx` into `yyy`, add the following configuration:

```yaml
renames:
  - from: foo
    to: bar
  - from: xxx
    to: yyy
```

To not perform any renames, leave out the `renames` property from the configuration file.
