# Flag import

To import your flags into Reflag from LaunchDarkly, you need a LaunchDarkly API key. The import tool will retrieve your flags and segments and map the rules to Reflag rules. It only take a couple of minutes to kick-start your migration.

### Notes

The import tool will warn you when it encounters rules that cannot be mapped directly to Reflag. This list shows when the import tool will warn you:

* Multivariate flags are skipped. These must currently be migrated manually. We can help if you get in touch.
* Flag rules that explicitly serve `false` are skipped
* Reflag supports percentage-based rollouts for flags, but not for segments. Unless the percentage is currently at 100%, percentage-based rule for segments will be skipped.
* Some LaunchDarkly operators do not map directly to Reflag. Here are the concessions:

<table><thead><tr><th>LaunchDarkly</th><th>Reflag</th><th data-hidden></th></tr></thead><tbody><tr><td><code>lessThanOrEqual</code>/<code>greaterThanOrEqual</code></td><td><code>lessThan</code>/<code>greaterThan</code></td><td></td></tr><tr><td><code>startsWith</code>/<code>endsWith</code>/<code>matches</code></td><td><code>contains</code></td><td></td></tr></tbody></table>

## 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.reflag.com/product-handbook/flag-import.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.
