Hello list, First of all: This is not a support request, even if it looks like! I will post my support questions to the users-ML if necessary, but my issue is the point with maybe inconsistent DB-scripts in the distributions. Here my scenario: I am upgrading from otrs 2.0.4 to otrs 2.2.4. And the differences between creating the database via the upgrade path (DBUpdate-to-2.1.mysql.sql, DBUpdate-to-2.2.mysql.sql, DBUpdate-to-2.2.2.sql ) to 2.2.4 and the direct create via otrs-schema-mysql.sql/ otrs-schema-post.mysql.sql are huge. A possible question could be why am I using the old 2.2.4. I have only hosted ubuntus with the default packages. Therefore I can only use ubuntu provided packages. And this is currently 2.2.4. The next issue is, that I wanted to migrate my otrs from 2.0.4 to 2.2.4 from a old to a new server installation/hardware. Therefore I exported my 2 GB huge otrs 2.0.4 DB and imported it on the new server with 2.2.4. Now I was trying to run the migration scripts provided with the 2.2.4 distribution (DBUpdate-to-2.1.mysql.sql, DBUpdate-to-2.2.mysql.sql, DBUpdate-to-2.2.2.sql). This failed. Therefore I thought it was my fault on any previous installation of otrs. And I analysed my way. Here may analysis: - Create a initial DB called initial (attached otrs-initial.sql) with otrs-schema-mysql.sql/otrs-schema-post.mysql.sql from the 2.2.4-tar.gz distribution - Create a migration DB from 1.1.3 to migrate to 2.2.4 called migration (attached otrs-migration.sql) with otrs-schema.mysql.sql (from 1.1.3) and the migration scripts (DBUpdate-to-1.2.mysql.sql, DBUpdate-to-1.3.mysql.sql, DBUpdate-to-2.0.mysql.sql, DBUpdate-to-2.1.mysql.sql, DBUpdate-to-2.2.mysql.sql, DBUpdate-to-2.2.2.sql) As you can see the both databases, which in my opinion should be identical are very very different. I have also attached a migration-script (otrs-initial_migrateInitial_ToUpgradePath.sql) which alters the initial DB to the migration DB. This is only for the purpose to show how huge the differences are. The script itself makes no sense. As a developer I cannot believe, that this can be correct. What have I done wrong? So far the questions from my point as a developer. Now my question, how can I upgrade my otrs 2.0.4 to 2.2.4 with changing the hosted hardware?
