I upgraded from Windows Media Rights Manager 9 SDK to Windows Media Rights Manager 10.1.2 SDK. Do I need to repackage my content?
A. If you upgrade to Windows Media Rights Manager 10.1.2 SDK your packaged content does not have to be repackaged and does not need to be re-encrypted. Headers for the packaged content do not need to be recreated for license chaining to continue working. Microsoft recommends that you update content headers to contain the current Uplink ID so that Windows Media Rights Manager 10.1.2 SDK clients can send the license state of the chained licenses to the license server. Legacy clients will ignore the new state information. Newer clients will identify the cause of what triggered the license request to the license server. By using the license state information, the license server will send only the license(s) (root, leaf, or both) that the client needs.
