We have projects those needs to be migrated from old version of Jira to Jira OnDemand. We need to migrate a few projects and also we have some projects in Jira OnDemand. My questions are:
1. Can we migrate project by project to Jira OnDemand?
2. Using Jira Import will it overwrite existing data on Jira OnDemand?
3. Is there any other way of migrating data, like using API or some kind of third party tool?
Please help me in giving more information on this. Thanks!
