Question about upgrading.

[Lubomirsb]

We have OTRS 3.3.4 installed. If we want to upgrade to 4.0.11 what we need to do ? Upgrade to 4.0.1 then to 4.0.11 or we can upgrade directly from 3.3.4 to 4.0.11 ?

You can do it directly. Just make sure you take care of the migration steps.

Thank you ! One more thing. Mysql version is 5.1.71. Should we upgrade to 5.5 ?

Don't know about recommendations. The manual says:

Code: Select all

Database support
MySQL 5.0 or higher
MariaDB
PostgreSQL 8.4 or higher
Oracle 10g or higher
The section in the manual about installation of Perl modules describes in more detail how you can set up those which are needed for OTRS.
If you install a binary package of OTRS, which was built for your operating system (rpm), either the package contains all Perl modules needed or the package manager of your system should take care of the dependencies of the Perl modules needed.

Hi,

you can use your old mysql version.

As far as I know mysql 5.0/5.1 is using MyISAM as storage engine, OTRS will complain about
it during upgrading. You should switch to InnoDB. It will work fine on a 5.0 and 5.1.

I heard from some mysql experts that InnoDB on a <5.5 is slower. So my recommendation
would be: update to 5.5 -> switch to InnoDB -> Upgrade OTRS
