Backup OJS 3.4 to a new server

I need help making a backup of OJS.
I already have the backup files, I need to export them to the new server, but they don’t work correctly

Used Version OJS 3.4

Hi @Carlos_Rojas,

There is some detailed advice on backing up OJS here: https://docs.pkp.sfu.ca/dev/upgrade-guide/en/#3-create-backups
