# Application Migration section of Patch My PC Publisher
*Applies to: Patch My PC Publisher V3.x*
The **Application Migration** section of the Patch My PC (PMPC) Publisher **Cloud** tab is used to help you migrate applications from Microsoft Configuration Manager to Intune using the *Migration* feature of PMPC Cloud.
{% hint style="danger" %}
**Important**
You will be unable to enable the **Application Migration** feature until you have connected Publisher to your PMPC Cloud company as detailed in [Connect Publisher to Patch My PC Cloud](/patch-my-pc-publisher/manage/cloud-tab/connect-publisher-cloud.md)
{% endhint %}
When **Application Migration** is enabled, Publisher inventories ConfigMgr applications and makes them available for migration to Intune through PMPC Cloud.
Discovery runs automatically every 60 minutes. Migration status and the number of discovered applications are shown for visibility and validation.
{% hint style="info" %}
**Note**
See [Setting Up ConfigMgr to Intune App Migration](/patch-my-pc-cloud/migration/setting-migration.md) for more details on setting up the Application Migration feature
{% endhint %}
## App Migration Database
When an app migration inventory runs, Publisher saves the inventoried ConfigMgr results in the Publishing Service's installation folder under the **Database** subfolder.
This folder contains two files:
* **AppMigration.db** stores the app migration inventory data and processing state.
* **existingApps.json** contains a JSON copy of the discovery data.
{% hint style="danger" %}
**Important**
For reliability, consider excluding the **AppMigration.db** file from antivirus or endpoint protection scanning. This prevents the **AppMigration.db** file from being locked during scheduled scans, which can cause inventory or migration operations to fail.
{% 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.patchmypc.com/patch-my-pc-publisher/manage/cloud-tab/application-migration.md?ask=&goal=
```
`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.
