# Prerequisites for existing FSLogix configuration

1. Back up your existing profiles. It is highly unlikely that profile data can be lost or corrupted, but it is best practice to have a valid backup prior to any change in the profile configuration.
2. Turn off the GPO configuration of FSLogix Profile Containers. This step is important because you cannot have both GPO and Parallels RAS management of FSLogix profiles enabled at the same time.
3. Before configuring FSLogix profiles for a server in a RAS Farm, make sure there are no user sessions running on the server. As a suggestion, you can make the transition in a maintenance window out of working hours.

## 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/ras-fslogix-containers-best-practices/v19/configuring-fslogix-via-parallels-ras/configure-managing-existing-profiles-by-parallels-ras/prerequisites-for-existing-fslogix-configuration.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.
