How to properly uninstall Multi-Domains

Hey Guys

I am in need of uninstalling multi-domains on a network I run. However, the last time I tried my site turned into a complete white screen with TONS of errors from various WPMU plugins such as headers sent and other function errors.

I remember that I did miss a step when doing it which was removing “define Sunrise” and I wonder if this could have been the cause of the errors? Before I try again I want to get complete step by step instructions on how to successfully remove this plugin. Thank you!
