Hello.
Hi,
We wanted to upgrade our 3.1.21 to 3.3.10.
Any intermediate upgrades required first?
Yes, you have to upgrade to 3.2.latest first (where latest is 16 at the
moment).
It is actually suffucient to apply the database upgrades in order.
I upgrade from an old largely unmaintained Debian wheezy package to
Debain jessie recently. I upgraded the package using apt, then grabbed
the upgrade *.sql from the 3.2 package, applied that, and then applied
the upgrade SQL from 3.3.
You do not need to double-upgrade the whole installation.
I¹m quite sure this is not correct. Probably it¹s not necessary to update
all the files. But beside the SQL there are other pre- and post-DB scripts
you should run. They are responsible for doing conversions (like the one
from FreeText to DynamicFields with upgrade 3.0->3.1), as well as other
important tasks (installing scheduler, Š). In short: to be sure, just do
the complete upgrade path.
AFAIK this process /is/ correct. E.g. a "clean migration" to an other
system would consist of
* Do a clean install of the newest OTRS version
* Transfer your settings files
* Replace DB of fresh installation by the one from the old install
* Run through all (!) required DB upgrade steps (3.1->3.2->3.3-> etc.)
This also makes sure you don't drag along lots of outdated files with
your installation.
If that works, the update procedure described by Dominik George should
work, too. The crucial point is that no matter how big the (file)
upgrade step is, the database upgrade procedure /always/ has to be
followed to the point. AFAIK there are no pre- or post-DB scripts to
consider. Everything is done by the main database upgrade script. E.g.
in the OTRS 3.1 manual it says "A database update script will transform
historic FreeText fields and related configuration settings into the new
structure".
