but I also changed my server… I moved on Vultr from ubuntu18.04 to centos 8.
I copied the files, and the database and changed the DNS to the domain on the new server.
I have not yet copied the contents of the tables matomo_archive_blob_2020_01, matomo_archive_blob_2020_02, matomo_archive_blob_2020_03 because they weigh too much, but it seemed to me that everything worked…
If you don’t copy over the reports for the last view months, you can’t really expcept them to show up in Matomo.
But as long as you copied over all of the raw visits, you should be able to recreate them by running archiving manually (and maybe invalidating the reports for this time range before).
Also make sure new data is still collected (so the visitor log still shows live data)
