Hi Luca,

Can’t help with your general question, but, f.y.i., the Calendar module is not available for 3.x, as far as I am aware.

Rudolf

Betreff: [otrs] Question about the upgrade process: overwrite previous version files or create a new tree?

Hi all,

I'm managing an Otrs 2.3.4 instance running flawlessly for almost 2 years on Ubuntu 8.04 LTS, and now I'm planning the upgrade to 3.0.4, with an intermediate upgrade to 2.4.9. We have some OPM package installed: Calendar version 1.8.3, FAQ version 1.5.4 and Support version 1.0.13.

The upgrade will be done through the tar.gz source package.

My doubt about the upgrade process is the following: do we have to overwrite the files in the /opt/otrs directory of the current 2.3.4 with the files from the 2.4.9 tarball or it is better something like this:

• unpack the .tar.gz of 2.4.9 in /opt/src
• mv /opt/otrs /opt/old-otrs-2.3.4         # rename the current production instance
• cp -a /opt/src/otrs-2.4.9 /opt/otrs-2.4.9    # clone the source in its own tree
• ln -s  /opt/otrs-2.4.9 /opt/otrs           # sym link to the current version
• copy Kernel/Config.pm Kernel/Config/GenericAgent.pm Kernel/Config/Files/ZZZAuto.pm from the 2.3.4 old version to the new version 2.4.9 tree in /opt/otrs
• set file permissions
• run the database upgrade scripts

In this case the problem I see is that the extra installed packages will be missing, so the question is: is it sufficient to reinstall them? even if the database has been already modified?
Are there any other files beside Kernel/Config.pm Kernel/Config/GenericAgent.pm Kernel/Config/Files/ZZZAuto.pm that need to be ported from previous version? something in /opt/otrs/var ?

The same process will be repeated from 2.4.9 to 3.0.4, obviously.

Thanks in advance for any help.
Cheers,
Luca
