We are about to do an upgrade to version 3.1.1 this weekend, and as we have built up quite a large database of our collections, we want to make sure we have a backup.
I am just checking if the command line code to backup the database is the most generic such as the one below or if there are any special options I need to activate to make sure we can rely on the backup :
sudo mysqldump -u [user] -p [database_name] > [filename].sql
Or is it better to use the phpMyAdmin?
While on the PhP subject, we have version
Should we upgrade that as well (to 8.0.13) prior to upgrading Omeka or can we stay as is for now?
