migration from shared to vps

21.0.0. Running on an Ubuntu 22.04.4 (Digital Ocean VPS). I am discovering that my database in mysql is missing all sorts of columns from various table. The issue is that I don’t know what I don’t know (i.e., I don’t really know what I am missing until I find out by using a module). This code have something to do with the fact that the database collation I was using was wrong when I installed Dolibarr originally using 20.0.4. Before upgrading, I fixed the collation error in the conf.php file. I thought the upgrade would fix the database columns, but it does not seem to have. I, unfortunately, have almost zero experience using Linux. I have managed to install Traccar and this app just using ChatGPT, but it has obviously made things harder.
