Service bus with new azure portal

Hi expert,

I just read this announcement

https://azure.microsoft.com/en-us/blog/service-bus-and-the-new-azure-portal/.

I would like confirmation as i'm not sure to understand if i need to do something or not.

Context:

I have already EventHub (and only event hub - no queues to tables) and a namespace.

Question 1:Does it mean that i MUST do something in august 2016 ?

Question 2: Does in mean that i MUST do something in November 2016 ?

Question 3: Does in mean that i MUST do something in March 2017 ?

Say another can i let my existing Event as they are ?

In case i need to do something (move EventHub to a new namespace): 

Question 4: could you confirm that Azure will let move move via Azure Portal ? 

Question 5: could you confirm that Azure will let move move via Powershell ?  Which cmdlt is it ? Shall we install new Azure Powershell version ? Does this version already exist ?

Thanks for your feedback.
