End of support for all Atlassian Server products. Organisations must migrate to Data Center or Cloud, often at materially higher recurring cost.
Perpetual Server licenses + maintenance
Data Center annual subscription or Cloud per-user
Atlassian has fully ended support for its Server product line. Unsupported instances receive no security patches — a compliance red flag for most audit frameworks. Migration targets are Data Center (self-managed annual) or Cloud (per-user), both of which convert prior perpetual spend into recurring subscription.
The entitlement mapping is rarely 1:1; Data Center tiers step up in large user bands, so right-sizing is essential before renewal.
