I found myself needing to migrate bugs from
Unfuddle, which exports them in a custom XML format, to
JIRA, which can import CSV (
documentation). I threw together a quick Java class to help me do this. It takes backup.xml generated from Unfuddle and creates a CSV which can be read by JIRA. It imports the following fields:
- Summary
- Status
- Description
- Milestone (as a custom JIRA field)
- Assignee
- Reporter
- Resolution (if resolved)
- Resolution description (as a comment)
- Creation time
- Resolved time (if resolved)
Furthermore it outputs the bugs in the order of the ID in Unfuddle, so that if you're importing into an empty JIRA project, the bugs will have the same number as in Unfuddle. It assumes the JIRA usernames correspond to Unfuddle usernames, though you can easily map differences by modifying the
lookupUser function. Once you generate the CSV, you can give the configuration file below to the JIRA CSV Import wizard to take care of the mappings. You'll want to update
- existingprojectkey
- user.email.suffix
to match your project. There are a few notable things that are missed with this tool:
- Time of day for creation/resolved
- Comments
The tool should run without modification and requires only Joda Time as a dependency under JDK 1.6. This is total slapdash, quick-n-dirty, git-er-done code for a one-off conversion. If anyone would like to extend this tool or generalize it, that would be great :)
