Atlassian Cloud for Banks – a Secure Migration from Data Center

Migration to Atlassian Cloud is becoming a necessity for the banking sector, driven both by vendor decisions and increasing regulatory requirements. The phase-out of Data Center solutions, the upcoming enforcement of the Digital Operational Resilience Act (DORA), and the need to strengthen operational resilience make Atlassian Cloud a natural direction for the evolution of banking IT environments.

What is Atlassian Cloud?

Atlassian Cloud is a SaaS-based cloud platform offering tools such as Jira, Confluence, and Jira Service Management, built on AWS infrastructure. It enables effective team collaboration, process automation, and IT service management without the need to maintain on‑premise infrastructure. Regular updates, a high level of security, and rapid access to new features make Atlassian Cloud a stable foundation for long‑term organizational growth.

Secure Cloud Migration – the role of an Atlassian Partner

As cloud adoption accelerates, regulated organizations increasingly seek solutions that combine technological flexibility with strong security and compliance standards. Atlassian Government Cloud addresses these needs by enabling efficient task execution and improved team collaboration without compromising compliance requirements.

A successful migration starts long before data is moved. The planning and preparation phase is critical, with certified Atlassian partners playing a key role. They provide architectural guidance, proven migration methodologies, and hands‑on support, helping to reduce operational and organizational risks.

Migration checklists further support this process by enabling IT and business leaders to assess organizational readiness, align teams, and plan subsequent steps to fully leverage the benefits of cloud adoption.

Bank Cloud Migration and DORA requirements

A key factor influencing migration decisions is the Digital Operational Resilience Act (DORA), which came into force on 17 January 2025 and applies to financial institutions and critical IT service providers. The regulation introduces requirements related to ICT risk management, incident reporting, digital resilience testing, and oversight of technology vendors.

A well‑planned migration to Atlassian Cloud can support compliance with these obligations by improving process transparency, system availability, and organizational readiness for crisis situations.

Why migration from Data Center is inevitable

Atlassian has officially announced the end of sales for Data Center products. This means no new subscriptions, limited availability of Marketplace apps, and the eventual transition of environments to read‑only mode. Banks still operating on on‑premises solutions must therefore plan their migration to the cloud or select alternative platforms well in advance, ensuring business continuity and regulatory compliance.

From on-premise to cloud – what does it mean for a bank?

Migrating from Atlassian Data Center to Atlassian Cloud is a strategic initiative that goes beyond a purely technical change. It impacts information security, operational efficiency, IT service management, and the organization’s ability to innovate.

Key benefits include:

• Security and compliance – automatic updates, data encryption, and audit readiness
• Operational resilience – geographic redundancy, backups, and disaster recovery scenarios
• IT efficiency – process automation and environment standardization
• Scalability and flexibility – easy adjustment of resources to changing needs
• Innovation enablement – access to new features, integrations, and AI-powered capabilities

Cloud as the foundation for future AI initiatives

Cloud migration is increasingly viewed as an investment in an organization’s future. Cloud environments foster better collaboration, faster decision-making, and provide a solid foundation for deploying artificial intelligence solutions. However, a key challenge remains the organization of data and elimination of silos, which ultimately determines the long-term effectiveness of AI initiatives.

Organizations that have already migrated to the cloud report tangible benefits:

• Increased scalability: 55%
• Improved reliability and disaster recovery: 39%
• Greater flexibility and agility: 36%
• Easier access to systems across locations and teams: 34%
• Cost reduction: 31%

Risks and concerns of Cloud Migration

Migration to Atlassian Cloud, especially in the context of Data Center phase-out, naturally raises concerns among financial institutions. These most often relate to potential loss of functionality, data security, costs, and end-user experience.

Sii Poland addresses these challenges by basing the migration process on robust practices and tools. Client engagements typically include:

• in-depth risk analysis and early mitigation scenario planning,
• migration plans tailored to the specific environment and business processes,
• pre-migration testing, validation, and post-migration quality assurance activities.

This approach allows potential challenges to be addressed well before the actual migration begins.
