Before	After

How to set up and validate locally

• Enable feature flag :bulk_import_projects in rails console: Feature.enable(:bulk_import_projects)
• In GitLab admin settings turn on Enable migrating GitLab groups and projects by direct transfer and save changes /admin/application_settings/general#js-visibility-settings
• Open "New group" -> Import (/groups/new)
• Use https://gitlab.com as source instance and GeK1Nis4j-SY1X4sqE5c as personal access token (this token is from separate user on GitLab instance with 0 real data available, so we do not expose any security risks here)
• Import top-level-group-1 (it contains project)
• Open History page /bulk_imports/history
• Observe the result
