Hello,
I was wondering if I can use the "External issue ID" of imported projects. Imagine we have imported several projects from Mantis to JIRA. The importer plugin created the issues (e.g. ISSUE-14) and stored the old Mantis id in the "External issue ID" field (e.g. 8772).

The subversion plugin is already working for new commits including "ISSUE-14" in commit message. Old commits to subversion always included the following "Mantis ID 8772: this is my commit message".
Is it possible to connect these old commit messages to my JIRA issues using the subversion plugin? If not, are there any workarounds?
Thanks in advance.
Best regards,
Michael
