I think that may have come through now as the item has removed from the “Pending Folder”. How do I move my staging site to the “Live” domain?

did you make migrate if you don’t try these steps:
Login to Greeny Host panel
Head to the https://my.greenyhost.com/manage then Hosting and click Start New Migration.
Select the option, Migrate a WordPress site using FTP and click Next.
Here you’ll be required to input 4 pieces of information:
Enter credentials for WordPress website migration
– Hostname: the FTP hostname, so the server you’d connect to via FTP
– Domain: the domain name of the site you’ll be migrating
– Username: the FTP username you’ll use, it is very often the domain of the site e.g. example.com
– Password: the FTP password you’d use to connect to FTP.
Once you’ve entered those details select Next.
The Migration Centre will then show you which packages will be migrated across, simply select Start to begin the migration.
