How to migrate Office 2010 Pro application most recently opened document (MRU) to Office 2013 applications

I am upgrading from Office 2010 Pro to Office 2013 Pro. In my test, we discovered that the MRUs are not getting migrated over from the Office 2010 Pro applications into the Office 2013 Pro applications.   I am using the Microsoft Office 2013 OCT to do the configurations.  In the OCT, I have "migrate user settings" checked, but that did not work for the users MRUs.  I came across the following link

That suggests manually creating the Migration key with sub keys like below

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\15.0\Common\Migration\Word]
"UpgradeVersion"=dword:0000000d
"Lang"=dword:00000409

On the test machine that I was using and had installed Microsoft Office 2013 Pro on, I found the keys listed as follows

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Office\15.0\Common\Migration\Word]
"UpgradeVersion"=dword:0000000e
"Lang"=dword:00000000

1) I would like to know which is correct subkey ("UpgradeVersion" and "Lang") to use?

2) Since I am using the OCT, can I add or import them into the OCT add registry entries section?

Thanks for your help.
