Atlassian Server officially reached end-of-life on 15 February 2024. Continuing to run it still works operationally, but security updates and Atlassian support are off the table. The two viable paths in 2026 are Cloud or Data Center (enterprise on-premise).
Cloud vs Data Center: quick comparison
- Cloud Standard: up to 35,000 users, no infrastructure work, automatic updates
- Cloud Premium: 99.9% SLA, sandbox, audit logs, IP allowlisting
- Cloud Enterprise: 50,000+ users, no downtime, advanced governance
- Data Center: for enterprises requiring on-prem data residency, deployed on a Linux/Windows cluster
Data residency concerns for VN enterprises
Cloud Premium and above lets you pin data to a specific region. There's no Vietnam region today — the closest is Singapore (ap-southeast-1). For most VN B2B use cases that's acceptable. Banking and government typically opt for Data Center instead.
Migration tooling
- Jira Cloud Migration Assistant (JCMA) — Atlassian's official tool
- Confluence Cloud Migration Assistant (CCMA)
- Always run trial migrations to a test site first — at least two dry-runs
- Plan ~4-8 hours of downtime for a 200-500 user environment
Digi43 supports planning, license sizing, and migration execution for Jira/Confluence across all three Cloud tiers. Get in touch for an audit of your current Server entitlements.
