# 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:
