We have a project in Jira Service Management under which there are about 7000 issues.
These issues contain attachments, links, internal notes, attachments + links in internal notes, as well as around 15 custom fields we have created.
We would like to migrate the whole project (all issues) to Jira Software project without losing any information we have. Both the Service Management and Software under Same URL
Please advice the best way to do so if possible and the problems we may confront.
Which solution could work? Export/Import .xml? or with backup and restore backup?
Please help.
