You can manage teams in the Fleet UI by selecting **Settings** > **Teams** in the top navigation. From there, you can add or remove teams, manage user access to teams, transfer hosts, or modify team settings.
You can add hosts to a new team in Fleet by either enrolling the host with a team's enroll secret or by transferring the host via the Fleet UI after the host has been enrolled to Fleet.
To automatically add hosts to a team in Fleet, check out the [**Adding hosts** documentation](https://fleetdm.com/docs/using-fleet/adding-hosts#automatically-adding-hosts-to-a-team).
> If a host was previously enrolled using a global enroll secret, changing the host's osquery enroll
> secret will not cause the host to be transferred to the desired team. You must delete the
> `osquery/osquery.db` file on the host, which forces the host to re-enroll
> using the new team enroll secret. Alternatively, you can transfer the host via the Fleet UI, the
> fleetctl CLI using `fleetctl hosts transfer`, or the [transfer host API endpoint](https://fleetdm.com/docs/using-fleet/rest-api#transfer-hosts-to-a-team).
