Pogoplug E02: how to swift arch linux to openwrt

already install archlinux and boot from USB drive, it's possible to swift to openwrt, either on nand or usb drive?

already have a look on https://openwrt.org/toh/hwdata/pogoplug/pogoplug_pogoplug_e02, but didn't find a way to do it.

is there such tutorial to do it step by step ?
