Welcome to the Autodesk Forums!
Glad you came here to find it:
Many look but few seem to see.
Download the Autodesk TrueView software.
Open the TrueView application.
In the upper left corner there is a menu button that says DWG Convert. Click the button.
DWG TrueView will now open a menu window to convert your file according to default settings. Make the selection for which version of AutoCAD to convert to.
Make any adjustments you need to make to the default settings.
Press the "add files" button and select the files you want to convert to the files menu,
Wait for the conversion to complete, and open the file.
Please don't reply to this message to contact me as I will not monitor it.
As mentioned in the post above, DWG TrueConvert software is now included in Autodesk DWG TrueView. This is no longer available as a stand-alone software.
Here is the link with with the instruction on how to get the tool:
