osTicket v1.12 is released on April 24, 2019, it’s open source ticket system. You can find full release notes at https://github.com/osTicket/osTicket/releases. For osTicket version 1.12 PHP version 5.6 to 7.2, 7.2 is recommended.
Upgrade process is very simple, I am doing 1.10.4 to 1.12
- Make sure you have a good backup of Database and files of osTicket
- Then put the system in the offline mode: by going to /scp/settings.php
- Download the new version from https://osticket.com/download/ and choose the osTicket Core, v1.12 (Latest Release)
- Upload to your server v. 1.12 and replace current files/folders from Upload folder from your downloaded, and exclude the script folder/files
Make sure you have the correct permission, then go to the URL/SCP of the osTicket system and log in, you should see osTicket Upgrader, make sure your Prerequisites are all good, if any errors correct it, then click Start Upgrade Now
Then you will get Migrate to osTicket v1.12, click Upgrade now
Then if everything goes well you should see Upgrade Completed
Delete the /setup folder and update any customization you may have, test it, then once all is good you can put the system back online. If you have customized PHP core files, those need to be re-applied after the upgrade. Also, make sure your plugins are good, if needed upgrade do so, make sure it supports the ent version. Good luck
