Azure File Sync - Migrating from Folder Sync to Volume Sync

Hello,

We've been trying out the Azure File Sync service at the folder share level and am interested in changing to synchronize the entire volume. This will eliminate the need to create new File Shares and Sync Groups with each new folder share creation. We are using Cloud Tiered Storage. Is there a documented process on how to perform this action? If we need to create a new storage account and/or file server, I'm ok with that. I'd like to avoid recalling > TB of files.

Thanks.
