Greetings. We have a client looking to upgrade from MOSS 2007 to SharePoint Server 2013, and I know that there is no direct upgrade so they'll need to go from 2007 to 2010 to 2013. In doing so, will they need a different product key for the 2010 install or will their 2013 key work on 2010? Just trying to map out how the process is going to work.
Thanks,
Mike
