I'm wanting to migrate a site from one WordPress multisite install (Dev) to another (Staging). I've read these posts
How to migrate Wordpress Blogs into Multisite without using the GUI-Import/Export Feature which is about migrating a single site (rather than a site in an existing multisite)
and this one Copy site from one multisite to another which doesn't do a complete job (i.e. you have to deal with menus, etc separately).
Any improvements on either of these answers for migrating a site from one WordPress multisite install to another.
