# Moved block configuration reference
This topic provides reference information for the `moved` block.
## Introduction
The `moved` block programmatically changes the address of a resource. Refer to [Refactoring](/terraform/language/modules/develop/refactoring) for details about how to use the `moved` block in your Terraform configurations.
## Configuration model
The following list outlines field hierarchy, language-specific data types, and requirements in the `moved` block.
- [`moved`](#moved): map
- [`from`](#moved): string
- [`to`](#moved): string
## Complete configuration
When every field is defined, a `moved` block has the following form:
```hcl
moved = {
from = <old address for the resource>
to = <new address for the resource>
}
```
## Specification
This section provides details about the fields you can configure in the `moved` block.
### `moved`
Map that specifies addresses for the resource. The following table describes the fields you can set in the `moved` block.
| Field | Description | Type | Required |
| --- | --- | --- | --- |
| `from` | Specifies a resource's previous address. The syntax allows Terraform to select modules, resources, and resources inside child modules. | string | required |
| `to` | Specifies the new address to relocate the resource to. The syntax allows Terraform to select modules, resources, and resources inside child modules. | string | required |
Before creating a new plan for the resource specified in the `to` field, Terraform checks the state for an existing object at the address specified in the `from` field. Terraform renames existing objects to the string specified in the `to` field and then creates a plan. The plan directs Terraform to provision the resource specified in the `from` field as the resource specified in the `to` field. As a result, Terraform does not destroy the resource during the Terraform run.
## Example
The following example moves an AWS instance from address `aws_instance.a` to `aws_instance.b`:
```hcl
moved {
from = aws_instance.a
to = aws_instance.b
}
```
