We are moving our Jira instance onto a locally hosted version, instead of the cloud hosted version. Unfortunately it seems as though the latest build we can get for the locally hosted is well behind the cloud based version we're currently on. This means it's NOT possible to migrate each project in its entirety across to the local version.
Currently we have 1600 issues across multiple projects that we need to keep for historical purposes.
These issues contain comments, history of workflow and attachments (eg wireframes and so on) which is invaluable data to the business.
Is there a way we can create a new project in our locally hosted version of Jira, import all the issues including their comments and attachments. The only import functionality I can see is via CSV/XML. This would not contain all the comments and all the attachments.
There must be a simple way of getting around this problem, that doesn't involve going through and downloading attachments from every issue.
I also noticed there doesn't seem to be a way to get a report on which issues in Jira do have attachments.
