One of my personal MSDN, and one is my employers. I do not want to blend what I do for my employer from what I do on my own. How can I separate the two so I have full access to my benefits?

Hi,

 I believe you want to transfer one of your MSDN subscription to a different Microsoft Account (email ID).
 In that case you will have to contact support by creating a free Billing Support Ticket and an Azure Support Professional should be able to help you.

 Refer to the Below article for more information.

Hello,

You cannot own two MSDN subscriptions under single Live account. If you are service admin in another subscription and have questions on managing them, then please rename your MSDN subscription to something else

1. Login in to https://account.windowsazure.com using your Live ID.

2. Click on "Account Center".

3. Choose "Subscription" option.

4. Select the Azure subscription in which you would like to rename the subscription name.

5. Click on "Edit Subscription Details".

6. After changing the subscription name click next and complete the wizard. 

Alternatively, you can filter to a subscription on top right using subscriptions tab.

Regards,

Lancers!
