Hello,
I logged in to my matomo site recently and was told to do an update from 3.x to 4.2.1. I followed the automatic procedure and it took a few minutes and completed. However, once this was done I seem to be missing all of the past analytic data for all of my sites.
I looked at other topics on this and did the manual update steps, but still nothing has come back. It only seems to be tracking data from the update forward.
A look in the database indicates that there are archive tables names something like “mt51_archive_blob_2018_01”. Is there a way to get this data back in to portal?
