Re: Test site question
I’d suggest installing phpMyAdmin locally and importing your database with that or you could use a desktop database management application like SQLYog.
You’ll need to update any references to your live hosting url (domain.tld) in your SQL file to reference your local dev url (localhost.localdomiain).
Also, if you’re running under Windows and have WPMU set to use sub-domains you’ll need to add entries for each subdomain in your hosts file manually.
Andrea Rennick over at wpmututorials.com has just written a pdf ebook on installing MU that you might find helpful too.
