Is there a way to recalculate SLAs on closed tickets?

[Al Gresto]

My company had their SLAs set up incorrectly for about three months. I recently changed them to the correct settings, making all current and future SLAs correct. The problem is, we now how 3 months worth of bad data in the old SLAs. Is there a way to recalculate the SLAs on these past 3 months of tickets that are closed (i.e. cancelled or resolved)?

If you adjust your SLAs, Jira will ask to recalculate your SLAs retrospectively, easy as that :)

You'll get a prompt when you save and it will say:

Save SLA changes

You changed your SLA configuration. Confirm your changes and we'll recalculate your project's SLAs.

  Review all changes

• Modified goal(s):
  • JQL: issuetype = Incident, Goal: 6h, Calendar: Sample 9-5 Calendar
  • JQL: issuetype in ("Service Request", "Service Request with Approvals"), Goal: 12h, Calendar: Sample 9-5 Calendar
  • JQL: All remaining issues, Goal: No target, Calendar: 24/7 Calendar (Default)

I wish it was that easy. It only retroactively recalculates SLAs for tickets that are still open. All resolved, cancelled, closed tickets do not retroactively update SLAs. I just tested it again and same results - no change in closed tickets. 

Is there a way to retroactively recalculate SLAs on tickets that are closed?

Ah OK, missed the key part of closed.

Looking at other discussions, it seems the answer is no.
