I'm in the process of setting up a multi-site WordPress environment. I have a number of stand-alone sites that I'd like to roll into the new multisite as sub-domains. I'm fairly skilled with WordPress - can someone (at a high level) provide me with the steps to do this? For example:
Export WordPress (posts/db, etc) from stand-alone sites.
Import WordPress (posts/db) into multi-site.
Map the old domain to the sub-domain.
I think there's more than this but starting at this level would be great.
