Upgrade OTRS 2.2.7 -> 5.0.9

[kkucza]

Hello,
we are facing some problem, as we are using still the ancient OTRS 2.2.7, and maybe this is a proper time for XXI century to come ?

I made a new machine with CentOS7, and set up there OTRS 5.0.9 - looks great, and is working. The problem is, that our employees want to hold their tickets history. Just great, we have a boycott here if the we can't make it

So - maybe you know, if there is any simple way to migrate the database from OTRS 2.2.7, and use it on second machine with 5.0.9 ?
Both machines are using MySQL as database engine for OTRS.

you have to follow the full migration path

2.2.7 -> 2.3.latest -> 2.4.latest -> 3.0.latest -> 3.1.latest -> 3.2.latest -> 3.3.latest -> 4.0.latest -> 5.0.10 (will be released today)

May I update just the database with some perl script ? Without updating the software - than I would dump and import the DB into new server - is it possible ?
I was trying to find old update scripts for 2.3, 2.4, but links was invalid.

no, you have to follow full upgrade path. You can download all versions on http://ftp.otrs.org

If you're interested in a working system after the upgrade stick to that what jojo wrote.
