Migrating Wordpress Multisite from staging to Go- Live

For the last 6 months we have been working on a multisite now we are ready to go live.
Development was done on stage.mydomain.com and want to copy over to http://www.mydomain.com. My sub blogs are setup with subfolders and I am not using multi-db server.
I am trying to develop a checklist that will facilitate a successful go-live tonight. I will appreciate any advice in achieving this!
Thanks in advance
