There are situations when you may need to modify issue history, e.g. when you needed to quickly do a simple import that did not include history, but later realize that it would be possible to program a more sophisticated import that retains history.
How can you do it in Jira cloud? This question has been asked before for Jira Server, and there the only way seems to be to modify the underlying database, which Jira cloud users cannot access.
I have some ideas about this, but please let me know what you think.
Current state of Jira Export/Import
Jira can export:
Jira can import:
XML + attachment files (the whole database backup), though it does currently not work for me.
CSV (including creation date, but apparently not history)
JSON (apparently with history)
Trello (no creation date or history)
- Other Jira instances
Potential options for fixing history
Rewriting history via API or GUI
Backup, rewrite history in the XML backup files and restore
Re-importing
Export recent history via API to JSON import format, merge with old history, re-import (issue keys will change)
Note that Atlassian is looking to completely overhaul the backup/restore experience. I wonder whether they will change the backup format from XML to JSON.
