OTRS Upgrade 5 to 6 Problem AgentTicketZoom.pm

[tuts]

I tryed to Upgrade vom OTRS 5.0.24 to OTRS 6.0.2 on Centos6 with RPM.
Ater finish the RPM install and DB-Upgrade without error I can Use OTRS exect the Ticket View.
When I Click on a Ticket I get an Error 500
Logfile says:

Code: Select all

Can't call method "FatalError" on an undefined value at /opt/otrs//Kernel/Modules/AgentTicketZoom.pm line 44.\n

I think there is any Setting wrong for AgentTicketZoom, because i Can Use the Large AgentTicketQueue View to read an Answer a Ticket (After successfull sending an Answer i get Error 500 because of AgentTicketZoom).

All Settings are on Default

I installed ITSM 6.0.1 maybe this can be the Problem ?
Deinstall don't solve because the ITSM-Settings remain in config ...

can anyone an Idea and can help me please to solve this Problem ?

Hi,

Did you upgraded your Perl version on the CentOS 6 system? Without this you can stop the migration, because the default version is too old for OTRS. For OTRS 6 you need CentOS 7.

Sorry i have Perl Version 5.16.
so this is not the reason.

I have solved my problem by manual backup ticket/artikel database tables, reinstall otrs and afterwards restore the ticket/artikel tables ...
