Atlassian is sunsetting Data Center outright; Cloud migration isn't a like-for-like cost swap
What this means: Teams running Data Center should start budgeting for Cloud now. The ~28% cost premium is a third-party estimate, not an Atlassian figure — get your own quote before assuming it holds for you.
Atlassian is retiring Data Center entirely on a three-year phased timeline rather than just raising its price. Bitbucket Data Center is the one exception: it keeps a separate hybrid license instead of following the sunset schedule. Atlassian is offering a 10–20% first-year discount on Cloud Enterprise for customers who migrate by June 2027, but that incentive doesn't fully offset the underlying cost shift: independent analysis puts the average Cloud premium over equivalent Data Center pricing at around 28%, a figure Atlassian itself has not published or confirmed on its own pricing pages.
Disputed figure: Atlassian does not publish or confirm this figure on its own pricing pages. The ~28% average Cloud cost premium comes from independent third-party analysis (Computerworld and The Jira Guy), not from Atlassian directly — treat it as a credible estimate, not a vendor-confirmed number.
