How to link the existing issues as a parent to the newly importing issues through CSV

[Aravind]

I was able to import the issues as a child to the existing issues by manually adding the existing issueIDs column and mapping it with the parent link at the time of import. But I wanted to do it without adding manually in csv sheet as it is not a preferred way to do for 1000+ issues. Can anyone help making it simpler.

Dear @Aravind,

this is not possible over the CSV import mechanism. You have either find a plugin that suits to your needs or you do it with the REST API (and some custom script code).

Thanks Thomas,

Missed mentioning the purpose, I was working on migrating the projects from rally to jira. Exporting the issues as CSV and importing into jira. Can this be done using a plugin or REST API?

Sure! Its a two step action. First import the issus, then make the existing to the children of the new ones.

Everything you need to know can be found on atlassian pages. For experimenting I strongly recommend that you use a browser extension (REST Clients) to fire and manipulate REST requests.

So long
