Moving an existing wpmu network blog to new domain

Hi,

I have a development blog under the wpmu network – currently as a subdomain (blog.maindomain.com)

This blog is now finished and should work on its “real” domain (www.blogdomain.com).

Can you give me a hint how to proceed?

– Change blog URL in settings of blog.maindomain.com to http://www.blogdomain.com

– Change Domain in Domain Mapping

– Replace blog.maindomain.com with http://www.blogdomain.com with a tool like https://interconnectit.com/products/search-and-replace-for-wordpress-databases/

Is this correct?

Thanks!
