# Importing from an Earlier Version of Parallels Desktop or Another Virtualization Application

With Parallels Desktop for Mac 27 you can use Windows that you set up using earlier versions of Parallels Desktop. However, importing, converting, and running previously created virtual machines from another virtualization application is not supported.

To import an existing Parallels Desktop virtual machine:

1. Open Parallels Desktop (in the Applications folder) and choose **File** > **Open**.
2. Select the virtual machine file you want to import, then click **Open,** and follow the onscreen instructions.

   * Parallels Desktop files end with `.pvm`.
   * Packed Parallels Desktop virtual machine files end with `.pvmp`.

   You can also simply drag a Parallels file to **Control Center** to add it to Parallels Desktop.
3. [Start Windows](/landing/pdfm-ug/parallels-desktop-for-mac-27-users-guide/use-windows-on-your-mac/getting-started/launching-windows.md).
4. Choose **Actions** > **Install Parallels Tools** and follow the onscreen instructions.

## 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.parallels.com/landing/pdfm-ug/parallels-desktop-for-mac-27-users-guide/install-or-import-windows/importing-from-an-earlier-version-of-parallels-desktop-or-another-virtualization-application.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.
