Today I've started upgrading OTRS from version 2.3 to 2.4 , 2.4 to 3.0 and 3.0 to 3.1. Everything went smoothly except the upgrade from 3.0 to 3.1 OTRS provides a few perl scripts which make the upgrade easier. I've used these scripts for each upgrade step. The upgrade from 3.0 to 3.1 fails at the following after using the upgrade script. 

scripts/DBUpdate-to-3.1.pl

The error is :

root@tickets:/opt/otrs# su - otrs
$ scripts/DBUpdate-to-3.1.pl

Migration started...

Step 1 of 24: Refresh configuration cache... 
If you see warnings about 'Subroutine Load redefined', that's fine, no need to worry!
Subroutine Load redefined at /opt/otrs/Kernel/Config/Files/ZZZAAuto.pm line 5.
Subroutine Load redefined at /opt/otrs/Kernel/Config/Files/ZZZAuto.pm line 4.
done.

Step 2 of 24: Check framework version... done.

Step 3 of 24: Creating DynamicField tables (if necessary)... done.

Did anyone else face the same issue? Thanks in advance

Can you please execute a SQL statement:

SELECT id, login FROM users WHERE id < 5;

because I think your user 1 does no longer exist?

  • This is what it shows `| id | login | +----+------------------+ | 1 | root@localhost | | 2 |asdsdass@datesds.com | | 3 | asdadasdsadasd | | 4 | asdasdsada |` – Valentin Bajrami Sep 07 '12 at 15:19
  • Could it be that you also upgraded the MySQL server? I know there are issues when you have some tables in InnoDB and some in MyISAM and then try to create foreign keys: http://bugs.otrs.org/show_bug.cgi?id=8528 – MichielB Sep 10 '12 at 08:06
  • Mike that's right! I've changed all the MyISAM tables to InnoDB engine type. This is what otrs suggested http://forums.otterhub.org/viewtopic.php?f=62&t=16730. Thanks for your Support! – Valentin Bajrami Sep 10 '12 at 11:51
