To import project data from Jira you just need to complete the following steps.
Step 1: select the project input function on UpDiagram and select Jira software
Step 2: Enter the required data
Step 3: select the project to import and install the remaining data (name member, name project, ...)
All data in the Jira management tool will be completely "transferred" to UpDiagram. No need to worry about re-entering data from the beginning, nor worry about losing data.
