I've been running Shibby v111 on my router for about a year. It was the first version of Shibby available when I switched from dd-wrt. I now see there are many more newer versions of Shibby available, and the fact that my v111 isn't even downloadable anymore, because I guess there were major bugs in it found after release, and is no longer a suitable version for distribution.
Is it going to be possible to upgrade from v111 to v121 without having to clear NVRAM and lose all my settings? Would tomato-E3000USB-NVRAM60K-1.28.RT-MIPSR2-121-Big-VPN.bin be the appropriate file to upgrade to? Do I have to do more of an incremental upgrade to keep my settings? I just really don't want to have to go back in and configure everything manually again.
Thanks for any and all info.
