Shimano has compatibility charts to show what works with what once you know what it is you want to compare.

specifically, on my Kona, Im thinking bout upgrading the RD and/or FD from acera mtn to alivio. But what I dont understand, should I consider alivio mtn or alivio trekking? Is there a difference? Yes, the acera works good now, but I have had a acera FD lockup/rust/freeze in the past- upgraded to alivio & problem solved. Also, it seems to me, mtn components are hard to come by, but trekking components are easier to find. This upgrade would sort of be a birthday present to myself.
