I know that this is a topic that has been talked about a lot but I need to export a project from MS Project to JIRA. I know that there are a few JIRA addons to make this job but they are paid and my company does not have money to pay a license for this addon. So, does anyone know if there is any script or any way to make this work?
you can use TaskAdapter: http://www.taskadapter.com
it supports Atlassian JIRA and Microsoft Project integration, among other systems. it is not free, but... it's a matter of how much of your own effort you want to spend on building a tool like that vs. buying a 3rd-party tool with support and all :)
