Upgrading SENTIENT Professional Edition to latest 4.3.x (4.3.1.1)
NOTE:
These upgrade steps are applicable for SENTIENT version 4.2.1+. In order to upgrade to 4.3.1.1PE you need to upgrade to 4.2.1.x first.
Prepare for upgrading SENTIENT.
Starting with version 4.3.1, the platform uses Angular 20 (upgraded from Angular 18). The core platform remains fully backward compatible and no upgrade scripts are required. However, custom UI code (widgets or custom CSS) that relies on internal component structure or CSS variable names may break. This can affect up to ~1% of users with heavy customizations. We recommend testing custom UI in a staging environment before upgrading.
Compatibility check before upgrading
If you are using Edge PE or SENTIENT ANALYTICS together with SENTIENT, verify that your target SENTIENT version is compatible with the currently installed versions of these components. Upgrade them if required to ensure compatibility.
