Hi, Im testing the upgrade procedure from out ours 2.0.4 to 3.1.2. I passed thought all the steps: 2.0.4 -> 2.1.x 2.1.x -> 2.2.x 2.2.x -> 2.3.x 2.3.x -> 2.4.x 2.4.x –> 3.0.11 And from 3.0.11 to 3.1.2 when i do the following: cat scripts/DBUpdate-to-3.1.mysql.sql | mysql -p -f -u root otrs I get this error: ERROR 1050 (42S01) at line 169: Table 'smime_signer_cert_relations' already exists Our DBA looked at the sql script and also seen the the instructions go ahead but they stopped when they are trying to create a table with foreign keys. The problem looks to be that the engine is MyISAM and that myisam do not support foreign keys. We are using mysql 5.5 (stable) Now the question is: how can i go ahead ? I change the engine from myisam to innodb for this table or did i miss something ? Please let me know.
