I'm trying to upgrade OTRS from 3.3 on CentOS 6.7 to OTRS 6.0 on CentOS 7.Here are the steps I've taken:
I first upgraded to 4.0 without any issues in the upgrade process, system is working as expected without any red flags in the Support Assessmet.
From there i upgraded to 5.0 also with equal success.
I have backed up everything
installed a new server with CentOS 7 and OTRS 5.0
Restored OTRS on the new server and everything is working as expected. No red flags in the Suppport Assessment.
Upgraded OTRS to 6.0 without errors in the upgrade process.
But when i try to view the ticket i get Internal Server Error. When i look at apache error log, these errors have the same timestamp as me clicking on the ticket:
Code: Select all
