# Migration Check and Reset

**Migration Verification** compares stored connector mappings with the currently connected Magento system.

### Purpose

Useful after a store migration, Magento upgrade, clone, domain change, or new API user.

### Procedure

1. Select the correct store configuration.
2. Test the connection.
3. Start the migration check.
4. Review missing or changed IDs.
5. Reload affected reference data or correct the mappings.
6. Test an individual synchronization.

### Distinguish Reading from Re-Mapping

The comparison itself does not modify any master data. However, the result list offers **Re-map Selected**, **Re-map All Changed**, and similar actions. These rewrite the Magento side and IDs of the mapping lines; existing BC targets are preserved.

{% hint style="warning" %}
The label "Read-Only" applies only to the check. Re-Map actions are write operations and must be verified afterwards in the Mapping Hub.
{% endhint %}

### Reset Magento Data

The reset requires the Web Store Code for confirmation but in version 27.10.0.16 it does **not** affect only that web store.

The following are reset tenant-wide:

* Magento IDs and synchronization fields on items
* Magento IDs and synchronization fields on variants
* All parent item records
* Image IDs and image synchronization status

The following are not deleted: configuration, mappings, Store View and MSI mappings, number series, order dashboard, download setup, and logs.

{% hint style="danger" %}
Only use after a backup and a coordinated rebuild. The confirmation code does not limit the technical reset to the selected web store.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.solutioo.de/magento-2-api-connector/magento2_en_us/configuration/migration-check-and-reset.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
