Gantt Suite for Jira: DC Version 5.0.x

Not sure what Jira version you’ve been using, Cloud or Server/Data Center?

The easiest way to see if you are on Jira Cloud or Server/Data Center is to look at the menu, if the main menu for Jira has category Apps you are on Jira Cloud. If the apps are directly at the main menu you are on Jira Server/Data Center.
