Can I add Veeam ONE with the current licenses?
You need either Veeam Availability Suite license or Veeam ONE license to leverage all product features. If you don`t have any, contact a sales manager, trial license is another option.
Where can I locate documentation to install Veam ONE without modifying the current installations?
Veeam ONE is a separate product and its installation does not affect Veeam B&R. Here is Veeam ONE Deployment Guide
