Only a Master MSP can provision an MSP. You can invite a new MSP to your Unified Management account or you can add an existing Unified Management MSP.
Provisioning an MSP
Navigate to Inventory > Products > All Products in the left navigation menu.
If you have an active monthly subscription, you can also provision an MSP on Inventory > Products > Monthly Subscriptions.
Enter details of a new MSP.
Do one of the following:
Click Create MSP and Exit to add the MSP and close the window.
An invitation is sent to the MSP. Once the invited MSP completes the signup, you can see the MSP under your account.
On successful saving, you get SUCCESS notification:
If you add a new user who does not have a Unified Management account.
Now, the new MSP is added to your All MSP list, but you cannot add a Tenant until the invited MSP user completes the Sign Up.
If you add an existing Unified Management MSP.
Now the new MSP is added to your All MSP list and you can add Tenant as needed.
