Gears & Axles - Will i run into any problems?

I recently purchased a complete rear end for cheap out of an m6 car with 3.42's and want to swap it into my a4 car that has 2.73's . Is there anything different between the two or should it be pretty straight forward swap? If there is differences could i just swap the carrier and gears out of th m6 rear end into myne?

Need to know what year the car and the rear end is.

channel differences could be an issue

4 channel=ABS & TC

vehicle ? channel
replacement rear ? channel

Well is it alright to just change the rear carrier and gears rather than swapping the whole rear out?? Or is there more to it i have a ratexh deluxe install kit

There is a lot more to it. Swap out the complete axle assembly.
