Both clients retain archived download links for migrating existing configurations, reinstalling legacy environments, and reproducing compatibility issues. Discontinued status means new system changes, core capabilities, and configuration-format updates may no longer be adapted, so new installations should prefer maintained clients.
Before migrating, back up configuration files, subscription URLs, and local override rules. After migration, verify basic proxy connectivity first, then restore DNS, TUN, scripts, and complex rules gradually to avoid bringing incompatible legacy settings into the new environment all at once.
