How to change service request key number?

[Aditya Padebettu]

While importing a CSV containing a few tickets to my project, I accidentally changed the key number. Rather than incrementing in the low thousands, Jira has jumped to more than 5 million. Every time a new ticket is created, it now starts at around 5 million. The difference is visibly shown in the screenshot below. I'm not even sure how I changed this during the CSV import.

Hi Aditya - Welcome to the Atlassian Community!

You can try to delete all of those and then start over with the CSV.

Hello! The issue is that we were trying to migrate a few tickets over to our Jira project, which already has actual tickets. Unfortunately I cannot delete those actual tickets because they are still open and unresolved by our IT Team.
