Migrate a single blog in a multisite installation to a single site installation

I want to migrate one blog i have in a multisite installation to its own single installation.
I would prefer not using the export/import feature in wordpress, it has given me some trouble with some categories not showing/changing their IDs. Would be great to do it by exporting the database files, but I just don′t know how to convert the multisite data into single-site.
I hope i′m being clear about what i′m trying to accomplish. Is it possible?
