Hello,
we have a bit older installation of OTRS (v. 2.0.4 from the sources) and want to upgrade to v. 2.2.3. Can this be realized in one step or do I have to install some versions beetween (e.g. 2.1. an than 2.2. etc.) Has anyone expierence in such a major upgrade, especially with possible problems with the database (mysql) etc.
I have found this post in this month with very helpful hints: http://lists.otrs.org/pipermail/otrs/2007-October/020536.html
Is there somebody having also any other experience - any feedback is welcome!
We run OTRS since the 1.3.x Series, upgraded to 2.0.4 and now to 2.2.1
recently. We are running with the same DB holding the Tickets ever
since and are happy with this.
The only thing you have to asure is to execute EVERY DB Upgrade Skript
since your actual Version:
.) backup everything eg.:
cp -r /opt/otrs/Kernel/ <destination>
/usr/bin/mysqldump -A -u otrs -p <destination>/backup.sql
cat crontab -u otrs -e > <destination>
.) make sure you backuped everything
.) update source to 2.2.x (our your desired Version)
.) execute upgrade skript
