Azure Service Bus Upgrade from Standard to Premium

Is there a solid upgrade path to migration a standard tiered service bus to a premium service when the number of entities created in the service bus (topics and subscriptions) is on the order of 50000-70000? The documentation says the built in migration supports "1,000 entities per messaging unit on the premium tier. To identify how many messaging units you need, start with the number of entities that you have on your current standard namespace." The max number of selectable messaging units for a service bus namespace is 16. Are we out of luck if we want to use the "Migrate to Premium" tool with that number of entities created on our standard service bus? Or does anybody know if there is another approach? If we chose the max, 16 messaging units, but have more than 16000 entites in our namespace, will the migration still work?

    @DeCarlo, Thomas I confirmed with the team that the limits are like the limits to that of the Premium Tier.

    So, the 1000 limit applies only to queues and topics, and if other entities are within the limits for the premium tier as mentioned here, you should be able to upgrade your namespace.
