Yes, it is possible to copy a production environment into a preview sandbox in Microsoft Dynamics 365 Business Central. This process is called "Creating a Sandbox Environment from a Production Environment."
Here are the steps to do this:
1. Sign in to your Business Central account with an administrator account that has permission to create a new environment.
2. Open the "Environments" page, and select "New Environment" from the ribbon.
3. In the "New Environment" dialog box, select the "Copy from production" option.
4. Select the production environment you want to copy from the drop-down list.
5. Fill in the required information for the new sandbox environment, such as name, location, and type.
6. Choose whether to include data in the new environment and select any additional options you want to apply.
7. Review the details of the new environment, and select "Create Environment."
The copying process may take some time, depending on the size of your production environment and the options you selected. Once it's finished, you should be able to access the new sandbox environment and begin working with it.
