WordPress "Must-Use" Tutorials
WordPress multisite how to - making sense of the network feature from what was wordpress mu
I love it when someone gets to me to-do list before me. 
It’s like an early birthday present. That being said, Jim over at BatavaTuesdays has written up a pretty thorough step-by-step process. I haven’t tested it myself, but it looks right so far.
The quick overview is to make a SQL backup of the WP blog, change the table prefixes and import it directly into the MU database. Yep, that’s pretty much it.
(Oh look, there’s another idea for a plugin if anyone wants to write one.

The way I approached it was a bit different.
I used the SQL import method for users only. Then migrated the posts and categories using the built in import option.
the only problem was assigning the users to the new blog. But it was a matter of editing their profiles.
You have to love the way the WP community bands together to help whenever possible.
Thanks for the heads up on this one
