My organization maintains several websites. Earlier this week we made a configuration change that inadvertently updated the tracking code on Site A to have the wrong siteId—the siteId for Site B. As a result, for about 24 hours, Matomo recorded visitors to Site A as visitors to Site B instead. We see in Matomo that Site A saw no visitors yesterday while Site B saw an erroneous spike in visits.
Fortunately these visits were all recorded with the correct URLs, so it’s pretty easy to identify them (since they have a completely different hostname from the rest of the visits to Site B). Is there any way to move the data from those particular visits back to Site A so our historical analytics are correct again? We’re probably even willing to drop into the database and manually update tables as long as we can be confident we’re doing it properly.
