The "Tenant Cloning" feature set was built to help MSP's scale and deliver consistent repeatable CaaS (Compliance as a Service) services to their client base by allowing an admin to Clone an existing tenant in order to create a new tenant. 

Any tenant can be cloned, however,  it is a best practice to build up a "gold image" so to speak to clone from to ensure the cloned data is built for the purpose intended. The cloning process allows a selection process.

To start cloning a tenant: Click the 3 dots action mention on a tenant and select "Clone Tenant"

A wizard will appear to walk you through the cloning process:

You can select or multi-select 

• Frameworks
• Controls
• Vendors
• Risk Sets (and custom risks)
• Documents (Policies / Procedures / Governance)
• Tenant Details (For new Tenant)
• Confirm Clone

Tenant Details: 

This is where you setup information for the new tenant you will create including the new Company Name and TenantID (suggested available tenant id's are displayed as shown)

Confirm clone:

A confirmation box appears to confirm you wish to proceed and that you understand the need to review data and ensure cloned data is sanitized to meet your needs.
