Greetings: We have been using OTRS 3.0.11 ITSM with very good stability and success, but now we'd like to upgrade to the latest version. The documentation states: "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)!" I don't have any problem with doing the upgrades in sequence as directed, but I would prefer not to do so on the production server (an Amazon EC2 EBS instance running Ubuntu). I'd rather build a test server on a current clean build of the Ubuntu LTS version, upgrade that all the way up to the current version on the test box, then ultimately I would like to install a clean 5.0.x OTRS instance on a new EC2 VM and copy over the database and our config and support files. After testing we can simply edit the A Record to point to the new EC2 VM and press on. Does this sound like an appropriate upgrade path? In order to build a test environment to do this should I start off by installing 3.0.11 on a test box, then restoring our OTRS directory and restore a copy of the database, then upgrade to 3.1, or is it possible to install a 3.1 instance and upgrade the database on it? Thanks in advance for your advice. Kind regards, Rob in Memphis
