Older links and newer cores

The proposal evolves; historical flow or xtls examples may not apply to current versions. Check the imported fields and core logs when a link fails.

Resolve certificate failures through correct trust/name settings. The newer Xray format used by 7.25.6 does not use allowInsecure as a workaround.

Release compatibilityCertificate settings

Upgrade, back up and restore

Use Backup and restore to save guiConfigs as a ZIP before upgrading; explicitly use the .zip extension on non-Windows systems. Record client/core versions and architecture.

For portable use, extract the new package to a new folder and restore the backup there. Keep the old folder until connections and subscriptions work. Upgrade installed editions with the same platform and architecture; uninstalling the app does not necessarily remove user data. Restore restarts the client; reopen manually if needed.

Version 7.25.6 changes core compatibility and generated configuration, so check the active profile, routing, DNS, subscriptions and TUN after upgrading.
