Transfer configuration settings from Balance 20 to Balance 30

I would like to upgrade from a Balance 20 to Balance 30. I read in a previous post that, with your assistance, it is possible to backup and transfer the configuration from the 380 to the 580. Could you please confirm that the same can be done so that I can easily upgrade from the 20 to the 30. It would be helpful to have this confirmed before I purchase the new router.
Thanks

Hello,

Yes this is confirmed. You just need to download the config file from the balance 20 and then send the file to [email protected].
