Currently have a multi site installation that I need to update the WP core and plugins. If I use your tool, cloud WordPress, how do I create a copy of my website to import into Cloud WordPress. Does Cloud WordPress provide access to files etc.
I’m not familiar with any staging environment in the “Cloud” for Multisite staging, but one thing you could consider is the LocalWP staging system, which is a free local development environment. It does include Multisite support.
