OTRS Centos Compatibility (Attempting Upgrades)

[Mohemoth]

Currently I am attempting to complete a project for the company I work for to get us off of OTRS 3.2.7. I've already gone through the entire upgrade process and made sure I can perform it but finally realized that there was not a compatibility with 3.3 on Centos 5.11. Now, the scenario at hand is that according to upgrades I am required to go to 3.3 to get to 4 and that's understandable. SO the end goal is to get to 4 and I understand to do so I will need to port this over to a newer Centos system. So now the problem. From the RPM libraries from what I can tell 3.2 is the highest compatibility on Centos 5. 3.3 is ONLY compatible on Centos 6 (but also 4.0 and up is compatible on Centos 6) and Centos 7 is only compatible with OTRS 4 and up. Now my systems engineer would prefer if I move this install to Centos 7 so we can run all of our new stuff on Centos 7 and OTRS 3.3 is purely just a means to get to 4. So The only thing I can figure to do is to spin up Centos 6 migrate otrs 3.2 to the Centos 6 machine, upgrade to 3.3, upgrade to 4, then spin up a Centos 7 and migrate to 7. NOW that sounds like a pain in the ass, so does anyone know if i cn get away with just migrating 3.2 to the centos 7 server and running the upgrade (using tarball of course as there is no repo) or is there going to be problems with that?

There should be not problem to do the whole migration on your CentOS 7 box. Here's what I did on my local VM (minimal CentOS 7 setup):

Code: Select all

[root@localhost ~]# cat /etc/centos-release
