1. Back up WTF and interface
2. Pop the WTF and interface from immersion in your World of Warcraft folder
3. Rename the account, server, and char names to their appropriate names.
4. Follow the ElvUI install instructions (doesn't matter what you pick) when finished /ec and switch the profile to IMMERSION
Please download ElvUI cause you have to. This UI wont work without it.
IF you make a new character kong will prolly not load right to fix this do:
/kong profile load IMMERSION.
