How to migrate from Jira without losing data
A practical plan for controlled Jira cutover: what to move, how to verify mappings and when to declare a new source of truth.
Key takeaways
- Agree on scope and cutover before export.
- Run preflight and mapping before real writes.
- Verify a sample, then declare the new source of truth.
Leaving Jira is not primarily a technical problem. It is a trust problem. The team needs confidence that active work, comments, relationships and context will not disappear, while leadership needs a clear moment when the old system stops being the source of truth.
1. Define scope
You do not need to migrate everything ever created. Separate active projects, the open backlog and history that still informs decisions. Keep archived projects in the original Jira export when they do not belong in the new operating model.
2. Agree on cutover
Choose a date and time after which new work is no longer entered in Jira. Run a trial import beforehand. At cutover, create a final export and repeat import. Stable Jira identities prevent duplicates.
3. Export all fields
In Jira Cloud use Project > List > three dots > Export > Export CSV - all fields. Do not modify the original UTF-8 file or resave it with an old Excel version.
4. Run preflight
Preflight writes nothing. It shows projects, item counts, statuses, types, priorities, users, sprints, comments, links and fields that need a decision.
5. Map intentionally
Do not force every Jira-specific detail into a one-to-one copy. A status such as “Ready for QA” might become “In review” or “Testing local”, depending on the process you want after migration.
6. Verify a sample
Open several epics, subtasks, items with comments, blocking relationships and sprints. If you use Jira Product Discovery, inspect opportunities, interviews and insights.
7. Declare the new source of truth
Migration is complete only when the team knows where new work starts. WorkThroughLine Jira Migration Assistant supports controlled cutover, not permanent administration in two systems.
Frequently asked questions
Do we need the entire Jira history?
No. Active work and relevant context come first; the archive can remain in the original export.
