As of Jira 8.4, when you import your data from an external issue tracker to Jira, you can do so in the CSV or JSON file formats only. We have deprecated all product-specific importers, so you cannot use them any more. Concentrating on CSV and JSON will give us enough bandwidth to improve these two most frequently used importers. We’ve already introduced some performance improvements to the CSV import to speed things up for you.
As we’re planning the backlog for the upcoming months, you can help us prioritise the required improvements to the CSV and JSON imports so that migration is seamless and straightforward.
Let us know any comments you have or issues you’ve experienced under this post. In this way we can focus on what’s going to bring most value.
