Hi Rose, Yes, you can see this: http://otrs.github.io/doc/manual/admin/stable/en/html/upgrading.html If you are running a lower version of OTRS you have to follow the upgrade path to 4 first (3.0->3.1->3.2->3.3->4)! You need to perform a full upgrade to every version in between, including database changes and the upgrading Perl script. -NM 2016-05-26 15:49 GMT+08:00 Rose Dowson :

Hi,

It's possible to upgrade my otrs 3.0.7 to 5 version ? If not, do you have an idea if I should go through the version 4 or maybe 3.3 ?

Thank you for the help. Best Regards,
