Now there may be a better way around this and im pretty new to Jira so bare with me if this is a stupid question.
We have recently changed a number of automation rules in Jira Service Desk - the rules run when ticket is created that set field values (ie when reporter in a certain group, set certain other fields to other values) which has worked great for any new tickets that are created.
We want to apply this to existing open tickets and then be able to apply to legacy tickets (all resolved and closed)
Is this possible, or is there another way to do it?
