We are moving to Jira Service Desk from Sugar and will be importing any open tickets into our new Service desk projects.
When customers reply to the Sugar tickets, sugar knows they are replies in the same way that Jira does - primarily because they have a key in the email subject, e.g. [SUGAR-1234]
When we cut over to Jira and import the tickets they will get new Issue Keys (e.g. JIRA-5678). At go-live, customers will still have emails in their inboxes from Sugar that don't have the new Jira Issue Key in them. When they reply to an email with "Subject: SUGAR-1234" it will go to our support email account (now monitored by Jira Service Desk) and Jira will think it is a new ticket because it can't find JIRA-5678 in the subject.
Jira won't let me import the issuekey as SUGAR-1234.
Is there any way of getting Jira to search for either JIRA-5678 OR SUGAR-1234 in email subjects?
This must be a common problem but I can't find any articles about it. Has anyone else worked round this in other ways?
Thanks in advance!
