You can create a new tenant database from an existing tenant database.  In most multitenant configurations, the first tenant is configured and then used as a template for others.

First, create a new database, then select the menu option below. 

On the Tenant Management page, select the tenant in the table, then click the Utils > Create New Tenant DB menu.

Choose how you prefer to create a new tenant database. Select between the “Current Database Server and Connection String” buttons. Provide the new database name. Click the Create button to initiate the process. 

A new tenant database is created, and a confirmation message appears in the top-right corner. 

You may verify this tenant database in SQL Server Management Studio. 

To create tables and data from an existing tenant, do the following. 

Select the tenant from the table on the Tenant Management page and click the Utils > Create Tenant Tables and Data menu option.

Select between the “Current Database Server " and " Connection String” buttons. Provide the new database name. Select the “Existing Tenant” button to create tables and data. Select the existing Tenant from the drop-down list.  Click the Create button. The tenant database is created with similar tables and data. A confirmation message is displayed in the top-right corner.
