Need help moving a multisite from sub-folder to public_html

I have a WordPress installation that I originally setup in a /wordpress subdirectory. Tonight I changed it to a multisite installation. Now I need to move the install to the webroot so I can use the multi domain and domain mapping plugin. We tried using this script https://github.com/interconnectit/Search-Replace-DB as recommended in https://codex.wordpress.org/Moving_WordPress but it ran into an error everytime - http://take.ms/NCzRt . Any further help regarding this is highly appreciated :slight_smile:
