I'm currently using a Asus RT-N15U on Shibby 1.28 (specifically Tomato Firmware 1.28.0000 MIPSR2-128 K26 USB Tor-VPN). I want to upgrade to a newer router, the Asus RT-AC56U.
The issue is looking on Shibby's site tomatoDOTgroovDOTpl/?page_id=69 (I can't post links), my current router uses an RT build while the new router uses an ARM build. I've tweaked my config just the way I want it, and it would take hours to re-input all of this manually. Ideally I just want to backup the config on my old router and simply restore it onto my new one.
Will everything transfer over as I'm planning, or will I have to rebuild from scratch? Ideas welcome.
