I have an active BizSpark account and I want to transfer this to another person in my company. How can I do this?
I tried to transfer my account using the instructions in this Microsoft article https://azure.microsoft.com/en-us/documentation/articles/billing-subscription-transfer/ but without success.
Update
In don't have the "Manage" option on my BizSpark account.

From the official FAQ: https://www.microsoft.com/bizspark/faqs.aspx
"To reassign your BizSpark administrator privileges, you will first need to add a user to your BizSpark account... Once the invitation has been accepted and the new user has received their confirmation of enrollment"
See screenshot below for details:
