Migrating App-V Packages– "OSD file defines incompatible OS requirements”

Ran into an interesting issue while trying to migrate some App-V Applications from ConfigMgr 2007 to 2012 SP1. Most of the App-V packages migrated fine, however a few of them reported an error

“OSD file defines incompatible OS requirements”

After taking a look at the OSD file, according to this list all of the OS version listed were fine. After some troubleshooting I found that all the failing Applications had multiple OSD files associated. This led me to the solution.

If you have multiple OSD files as part of an App-V Application, you must have the same OS requirements listed in all of the OSD files. Once we fixed the compatible OS list, the Application migrated successfully.
