While researching exchanging licenses between servers I came across "Historical Data." What is historical Data?
Data from the past.
Care to provide a bit more context? Maybe a link to what you were reading?
I believe it is referring to machine data generated in the past and stored somewhere in bulk, ie an archive of syslog data or a collection of daily csv reports from the last year sitting in a directory..
If it was in another context, let us know and we can help lead you to answer!
