Polarion Version Compatibility Matrix

Always verify compatibility with your specific Polarion and Gantt versions before upgrading in production. Contact Nextedy support for the latest compatibility information.

Compatibility Overview

Polarion Version	Minimum Gantt Version	Notes
Polarion 2310	24.6.0	Fully compatible; update Gantt to latest version
Polarion 2404	See application	Compatible with latest Gantt versions
Polarion 2506	25.9.0	Compatibility issues fixed in v25.9.0

When upgrading Polarion, always update to the latest Gantt version to ensure full compatibility. Older Gantt versions may not function correctly with newer Polarion releases.

Scripting API Changes (Polarion 2304+)

Starting with Polarion 2304, changes to the Polarion scripting environment require script migration for Gantt page scripts and config scripts.

Change	Impact	Action Required
Scripting API changes	Existing page scripts and config scripts may stop working	Review and update custom scripts after Polarion upgrade
Script execution context	Modified execution environment for Velocity scripts	Test all scripts in a staging environment before production upgrade

Use a test license to validate your Gantt configuration and scripts against the new Polarion version before applying the upgrade to production. See License Types and Evaluation Periods for test license information.

Admin page	Navigate to `/polarion/#/administration/gantt/setup` for version and license details

Pre-Upgrade Checklist

Step	Action
1	Verify target Polarion version compatibility with current Gantt version
2	Download the latest Gantt version from Nextedy
3	Install Gantt update in a staging environment
4	Test all custom scripts (config scripts, item scripts, page scripts, marker scripts)
5	Verify working calendar calculations
6	Validate dependency link behavior
7	Confirm resource view accuracy
8	Apply to production

Workflow Condition Compatibility

The Gantt provides a workflow condition that integrates with Polarion workflow enforcement. This condition is dependency-type-aware:

Feature	Description
Status gate enforcement	Prevents work item transitions unless linked predecessors are in allowed states
Dependency-type filtering	Only Finish-to-Start dependencies are enforced in forward checks; Start-to-Start and Start-to-Finish are excluded
Cross-permission enforcement	Dependency gates are enforced even when linked items are not visible to the current user

Configure the workflow condition in Polarion’s workflow XML with these parameters: link.roles (forward link roles), back.link.roles (reverse link roles), and valid.states (allowed status IDs). See General Administration Properties.

Configuration Example

Verify the installed Gantt version by checking the footer or navigating to the admin page:
