Hello, Demonkunga here. I've decided to make a video guide, showing how to change Instance to Instance.
Programs you will need:
MyWarcraftStudio
DBCUtil
CSVed
MPQ Editer
Model Edit Fix - Remember to put this into your WoW directory C:\Program Files\World of Warcraft\
TechSmith Screen Capture Codec - You may need this codec to watch my video
Exporting, Converting and Packing
