Migrating/Cloning a multisite (e.g., DEV to STAGING)

MIGRATING/CLONING A MULTISITE TO ANOTHER LOCATION (E.G., DEV TO STAGING)
I am looking for a WPMuDev plugin that works like UpdraftPlus (but for multisite) to migrate/clone an entire site -- files, uploads, db, etc. -- from one site (URL) to another (URL). As you would do to duplicate a site for staging. So far, I have attempted this with both Cloner and Snapshot. Had tech live chat but tech person disconnected chat before I could even read what was written!

The certainly could manually copy over files and import a database, but the beauty of UpdraftPlus is that is handles the site URLs for you too. It works beautifully on a single-site.

Please advise.
