Hello,
I recently migrate our jira to a new server (upgrade from version last 7.x to 8.0.2).
I got several issue
- no reindex possible (and no log error)
- when I try to check integrity, I see some technical error
- when I check to instance health I see one error related to attachment and the other are warning
- When I analyse log I found some error
Troubleshooting guide
