I have 2 very good RT-AC88U routers but the 5G range is not the best. They work reasonably well but I am upgrading to an RT-AX58U as the main router. I will be turning the other 2 routers into AIMesh routers. My question is, as long as both routers are on the same firmware (I'm running WRT-Merlin), can I just export the configuration file from the existing base router and then import it into the new AX router? Will it just transfer the settings from one to the other without having to set it up all over?
