I have a RT-AC86U with a 2GB USB drive attached. I don't stress the router much and only have and use diversion. The drive has a 1GB swap file and the rest is for jiffs storage. However, I am thinking that with more of Merlin's functionality going to be stored in jiffs, maybe 1GB is not enough and am thinking of replacing the drive. Is there a recommended way to replace the USB drive (as in clone the drive and expand the space outside the router) or is my best solution to do a complete reset of the router and start from fresh?
