Yes, you can. There is no limit on the number of Space On-Premises instances one customer or company can host, so you can definitely create multiple organizations for different departments or teams in your company if you need to. You can’t combine users on different subscription plans within the same Space On-Premises instance, however, and you will need a separate license key for each Space On-Premises instance.
Even though it is possible to create multiple Space organizations, we believe that your company will be able to accomplish much more with a single unified one, as your employees from different teams will be able to communicate and collaborate together in a unified environment.
You can also create as many Free organizations as you need for testing, or purchase different subscription plans for different Space On-Premises instances.
