Good morning,I'm trying to run through a test trial of backing up, upgrading, and downgrading osTicket on a toy server before I implement the upgrade on my production server. I have the latest release of 1.9.1 and I have a backup of my 1.8.x installation, including the mysql database (made using Softaculous with cPanel).Server type: Shared Lunarpages server (no SSH access)Server management: cPanelSoftware script management: SoftaculousFile managers: Filezilla and cPanel File ManagerI'm relatively new to databases and shared servers, so I appreciate your patience and any help you can offer. So far, I have done the following:Upgrade AttemptRun a backup of 1.8.x installationUpgraded to 1.9.1 (including automatic database migration) (successful)Downgrade AttemptsOverwrote 1.9.1 install with 1.8 data (failed to upgrade error)Purged everything and restored contents of 1.8 backup (failed to upgrade error)Purged everything in osticket, renamed database to _old and migrated data from backup to new database (fatal error)Purged everything in osticket, used phpmyadmin to copy old database contents to new database (fatal error)This is why we have toy servers. :) Thank you for any help you can give!
