What should be migration path from OpenWrt Backfire (10.03.1) to Gargoyle?
I have TP-Link WR841ND v5 (Atheros chipset), with OpenWrt installed from here
I was using openwrt-ar71xx-tl-wr841nd-v5-squashfs-factory.bin image to flash router directly from factory web interface.
What should I do to upgrade it - from OpenWrt/LuCI - to Gargoyle UI?
Should I use *-squashfs-sysupgrade.bin firmware from Gargoyle repository?
Is web flashing ok, or some other steps are required?
P.S. I have checked Gargoyle Install Guide
It doesn't mention TP-Link routers, or upgrade from OpenWrt to Gargoyle.
After migration from OpenWrt/LuCI to Gargoyle, I am ready to make detailed Wiki page on this process and final results

Thanks for any help offered!
