Is it possible to switch to the latest version of Tomato on a router that's already running DD-WRT? Using the default Linksys firmware on my WRT54GL v1.1, I had to upload a micro version of DD-WRT first. I imagine that, since I'm now running third-party firmware, I won't have to do that again to make the switch, but I thought I should check so as not to brick it.

This router is taking a back seat to a new AirPort Extreme (for the 'n' capability), but I still want to have the soon-to-be-Tomato device sit between the AirPort Extreme and my modem for the superior traffic graphing.
