With every new version of AutoCAD, we upgrade our CAD libraries to the current version. For the last several version upgrades we have used the batch conversion feature to accomplish this for thousands of files at once. For every version I've also had to create a profile that would "upgrade" the DWG's to the current version. I've never understood why this profile is not included in the program - as if the programmers assume that you'd only wish to downgrade to an older version. (See DWG Convert 1.png)
In this case, we are moving from AutoCAD 2010 files to AutoCAD 2013.
The conversion appears to execute, but does not appear to be working. (See DWG Convert 2.png) Files still say that they are from a previous version. (See DWG Convert 3.png)
