To transfer account ownership:

Prerequisites

• Roadmap can only have one Account Owner.
• Ownership can only be transferred to an Admin user.  The only differences between an Admin and Account Owner is that the latter can:
• Upgrade, downgrade, or cancel your account
• Designate other Admins
• To grant Admin privileges to an existing user, go to Resources Tab, and under any grid view, navigate to (or add) the "Privilege" column and select "Admin".
  

  
  

• Transferring ownership will not change or impact your current payment plan arrangement

Transfer Account Ownership

Current Account Owner goes to Account Settings > Personal Info, clicks "Transfer Owner", and selects the user to transfer account ownership to.
