We are working on a new project with one of our customers, and they have on-premise SharePoint server 2013 with SP1 and January 2016 cumulative update installed. But i am trying to know the history of this SharePoint farm, and if it was upgraded from earlier versions of SharePoint such as 2010 or 2007, or it is a SharePoint 2013 from day one.
now our customer do not have the answer,, so not sure if there is a way to know if this SharePoint 2013 server is 2013 from day one or it is upgraded from 2010 or from 2007 ? Thanks
now as shown above all the versions starts with 15, so does this mean that it is a 2013 database from day one ? second question i can not find any version which represents the following number
22.214.171.124 what does this represents ?
