OTRS upgrade from 2.3.x to 2.4.x

[jj99]

I successfully updated otrs 2.3.6 to 2.4.15 on SUSE linux but queue view is not showing ticket data , also the customer information not visible on queue view.
suggestion will really help me.

I doubt that it was succesful. Did you follow all steps on the UPGRADING file?

Please be also aware that OTRS 2.4 is very outdated (3.2.7 is actual version)

Thanks for reply. Actually I made a mistake while running database update script.

In update document it is mentioned to backup var folder as well but it is not mentioned to restore this var folder to lastest otrs version.

Also after update some pictures are not visible as you seen in the attached piture.

don't restore the var folder of an old OTRS version
