What is required to relocate a garbage disposal?
This project is fairly straight forward. You need to completely disassemble both sides including the in sink trims.  You will need an adjustable wrench, a large pair of pump pliers or monkey wrench, screwdriver, nothing special.  Be sure the electrical wire will reach the new disposal location, it not, you will need a j-box and some wire,  you will also need some plumber's putty to seat the drain trims.  You definitely will have to replumb the drains and traps, but you may be able to salvage a few pieces.  It's gonna take you a few hours so be prepared to spend the day without water in the kitchen.
