Upgrade Changes
This section outlines changes that may need to be applied to ICXT components during an upgrade from earlier versions of ICXT.
Upgrade from v4.0.x or earlier
Database schemas have been extended and need to be updated
The schema (particularly attribute length) of certain tables/fields has been updated to accomodate extended functionality. This leads to issues when attempting to use certain functionality (e.g. Move and Merge) in newer versions of ICXT.
Solutions
The ICXT installation archive contains fix-up scripts (db-setup/icxt-fixup1_DB2.ddl and db-setup/icxt-fixup1_Oracle.ddl) that can be applied to existing database setups in order to update the respective schemas.
Alternatively, the existing databases could also be deleted and then recreated based on the instructions in ICXT Setup Preparations - Database and the latest provided db scripts. Note ICXT almost exclusively stores transient data that is not critical and can be removed. However, some information stored for features (like scheduled backup) would be affected and cleaned up/lost as well.
Upgrade to Latest Version
To upgrade to the latest version, you can follow the same steps as the installation process documented in the Installation Scripts. You can skip the post-install steps mentioned in the installation document. Additionally, you can reuse the properties from the previous installation.
Note: Ensure that the upgrade process aligns with your production configuration. If any manual adjustments were made after the initial installation, the upgrade might revert those changes.
