 feature, ask an administrator to [enable it in application settings](../../admin_area/settings/visibility_and_access_controls.md#enable-migration-of-groups-and-projects-by-direct-transfer).

 Migrating groups by direct transfer copies the groups from one place to another. You can:
 
 - Copy many groups at once.
-- Copy top-level groups to:
+- In the GitLab UI, copy top-level groups to:
   - Another top-level group.
   - The subgroup of any existing top-level group.
   - Another GitLab instance, including GitLab.com.
-- Copy groups with projects (in [beta](../../../policy/alpha-beta-support.md#beta-features) and not ready for production
+- In the [API](../../../api/bulk_imports.md), copy top-level groups and subgroups to these locations.
+- Copy groups with projects (in [Beta](../../../policy/alpha-beta-support.md#beta) and not ready for production

   - On GitLab.com by default.
-  - On self-managed GitLab instances after an administrator first [enables the feature flag](../../../administration/feature_flags.md) named `bulk_import_projects`.
 
 Not all group and project resources are copied. See list of copied resources below:
 
 - [Migrated group items](#migrated-group-items).
 - [Migrated project items](#migrated-project-items-beta).
 
+WARNING:
+Importing groups with projects is in [Beta](../../../policy/alpha-beta-support.md#beta). This feature is not

 We invite you to leave your feedback about migrating by direct transfer in
 [the feedback issue](https://gitlab.com/gitlab-org/gitlab/-/issues/284495).
 
 If you want to move groups instead of copying groups, you can [transfer groups](../manage.md#transfer-a-group) if the
 groups are in the same GitLab instance. Transferring groups is a faster and more complete option.

 ### Prepare user accounts
 
 To ensure GitLab maps users and their contributions correctly:
 
-1. Create the required users on the destination GitLab instance. When migrating to GitLab.com, you must create users
-   manually unless [SCIM](../../group/saml_sso/scim_setup.md) is used. Creating users with the API is only available to
-   self-managed instances because it requires administrator access.
-1. Check that users have a public email on the source GitLab instance that matches their primary email on the
-   destination GitLab instance.
-1. Ensure that users confirm their primary email addresses on the destination GitLab instance. Most users receive an
-   email asking them to confirm their email address.
-1. If using an OmniAuth provider like SAML, link GitLab and SAML accounts of users on GitLab. All users on the
-   destination GitLab instance must sign in and verify their account on the destination GitLab instance. If using
-   [SAML SSO for GitLab.com groups](../../group/saml_sso/index.md), users must

+1. Create the required users on the destination GitLab instance. You can create users with the API only on self-managed instances because it requires

+   - Set up or use your existing [SAML SSO provider](../saml_sso/index.md) and leverage user synchronization of SAML SSO groups supported through
+     [SCIM](../../group/saml_sso/scim_setup.md). You can
