Need a little help with WPMU + NGINX

Hi WPMUDEV !

I am in the process of moving from a lame shared host to a dedicated one.

I have thoroughly read:

My current web server is
http://184.106.81.103/
which is running nginx, phpfpm, php,

I also have another dedicated sql server

Both servers are Ubuntu.

I am moving from Dreamhost to Rackspace.

It currently runs at http://tradr.com
It must work at http://184.106.81.103/ 100% before migration.

Should I post my /etc/nginx/sites-enabled/tradr.com
config files here? will that help?

Cheers

John
