Hi,
we have three Jira instances at hand we want to consolidate into one (new) instance. For the time being we do not have full admin access since the Jira instances are managed by a different team. We are project admin, though. We are looking for the easiest approach to migrate the tickets, their fields and the attachments.
May be someone else did something similiar in the past. I found several topics regarding migrating one instance to another but not much info or advice consolidating several instances.
