Migrating Multisite with Snapshot Pro


I need to migrate my WP Multisites to a new server. I have been reading all the documentation and wanted to quickly check a couple of things.

1. I see that Snapshot Pro now supports Multisite which is great. Can I use it do do a full migration of my Pro Site install with all the subsites. Or do I need to backup each subsite separately?

2. If use Snapshot Pro to migrate, do I still need to migrate database tables separately?

3. What is the best way to access the backup from the new installation. Do I need to download and upload or can I create a new (empty) WP Multisite install on the new server, install Snapshot Pro and point it to the backup?

Thanks for your help!

Kind regards,
