We've imported a large number of "legacy" projects from various pre-JIRA issue trackers. These have to be kept online for occasional references, but are never modified (read-only).
We'd like to move them to a separate JIRA-instance, federated with the active one so as to keep the main instance with active projects more nimble. However, we have only one 2000-user license.
Can we split the instance like this – the user-accounts are all maintained in the same company-wide Active Directory anyway – or would it require doubling the license costs even though the number of users is the same?
Please, advise. Thank you!
