Sep 21st, 2009

A custumer is about to migrate from CM 4.2 to 7.1, as far as I know so that I can get the license file I have to run DMA, but in the link https://tools.cisco.com/SWIFT/Licensing/PrivateRegistrationServlet?FormId=806.

where the license file is requested to paste the info generated by communication manager upgrade utility..??

Both application gets the same info???

Regards,

I have this problem too.

The upgrade utility is used to verify that the server meets the minimum requirement for the Cisco Unified Communications Manager version to which you are upgrading.

DMA actually exports the data and generates the license files needed to build the new version. Once you have the license file you need to submit it to cisco licensing to get a proper license file.
