Translate or convert GPOs from earlier versions

I need to translate many GPOs from previous versions of Office and Windows Versions.  Specifically, I need to be able to translate Office 2003 GPO settings to the corresponding (if one exists) in Office 2007 (yeah, kinda behind the times).  Seperately, I need to translate settings that were applied to XP but no longer apply to WIndows 7 (they are listed as applying to "Windows 2003, Windows XP,and Windows 2000 only"). 

Is there a document i.e., spreadsheet, that would help me with such a translation?  Any ideas?
