My message board has been around since 2004, running vBulletin until roughly January 2019 when I switched over to XenForo. When I view historical statistics, I can only see stats from when I installed XF and onward. Is there anyway to see the historical data? For example, here is a graph of the monthly posts from Jan 1, 2005 until today. As you can see there are no data points from before I installed XF. Is there anyway to "fix" that?
