Hello,
Do you have restore point file or backup archive? If it's restore point then nothing can be done because it can be loaded only to a RUT950 on which it was created. If you have a backup, then install same firmware version to the new RUT950 on which backup was made, download backup from the new device (WebUI System->Administration->Backup) and replace /etc/config/system file of the old backup with one from the new backup. Then it'll be possible to load old backup archive to the new router.
