This is my first post and after a search without success I take courage to write here my issue with Moodle 3.8.1
I made a migration of a production Moodle installation from the production server on a backup/standy server. I used the "quick and dirty" method and i made this steps:
1) rsync from source to destination server (folder's path is the same on both servers)
2) mysqldump from source server;
2.a) search in sql file of all refereces of the old FQDN (eg. moodle.example.com) and a massive replace using new FQDN (bck-moodle.example.com);
2.b) SQL import of the modified sql file into destination server;
3) modified the config file adjusting with new parameters and references;
After all, browsing the url https://bck-moodle.example.com moodle don't show the home page but the installer page.
I made a check on all configurations, files, sql, etc but I wasn't able to solve this issue.
Someone have any idea about this problem?
Last note: on source server everything works fine and all prerequisites are validated. The destination server is a specular clone of the source server (same hardware, same Linux Distribution and version, same php packages installed, same Apache versions and modules...
