As I recall, Shadowrun is actually a future version of Earthdawn.
IOW, you could probably use it as is, just changing the names of locations. Humans, Orcs, Elves, and Dwarves exist in the game as-is, so you don't really need to do anything with them at all.
That said...I'd jazz things up a bit.
I'd make the Net into another plane of reality that manifests itself as a glowing overlay of reality when manifested by a Hacker. That would let EVERYONE interact with the Net and whatever is in it, to an extent. Viruses could become like the Grid Bugs from the Tron video game. To continue along those lines, familiars could be Bits, Paladin mounts = Light Cycles, and ICE becomes Elementals...and AI become Djinn.
Even without the Tron influence, you'll need to work with the Warforged, Changelings and Shifters.
Warforged: I'd make them into Cybermen. Take a race or nation from Eberron and wipe them out (genocide? plague? that's your call), but have a select few managed to shift their brains (or just their spirits?) into mechanical bodies.
The only trick will be setting them apart from all the other Street Samurai in the game. You may want to make them an incompatible tech (PC vs Mac?) or simply ensure that their culture is reflected in their skills, etc.
Changelings: They're either pure biotech or magical biotech.
Shifters: The result of experiments by someone like Dr. Moreau...
