Question about licensing and upgrading on ThinkPad T450

Hope someone can help me.  I have a ThinkPad T450 that has a BIOS license for Windows 8.1 RTM Pro OEM.  The actual OS currently installed is Windows 7 Enterprise (see the attached screenshot).  The question is: if I update using a retail version of Windows 8 Pro and then update to 8.1, will I need to use the retail key or should the OS automatically validate using the existing OEM key installed?  I don't want to have to reinstall all my apps again.  Thanks in advance.

Windows 7 Enterprise runs entirely on a seperate licensing branch.

 

Remove Windows 7 Enterprise before installing Windows 8.1 Pro. It will activate right off the shelf.
