Why Move? 5 Cloud Advantages for Jira & Confluence

Scalability Without Hardware Constraints
Atlassian Cloud eliminates hardware limitations entirely. Scale instantly during peak periods—no more procurement delays or capacity planning headaches. Whether onboarding 50 new developers or launching a major initiative, elastic infrastructure adapts automatically.
Enterprise-Grade Security Features
Cloud platforms deliver native SSO, Atlassian Shield, automated vulnerability management, regular penetration testing, SOC 2 Type II and ISO 27001 certifications, and advanced threat detection.
  • Automated vulnerability management
  • Regular penetration testing by Atlassian
  • SOC 2 Type II and ISO 27001 certifications
  • Advanced threat detection capabilities
Reduced Maintenance Overhead
No server patching or infrastructure to maintain. Atlassian handles all upgrades and optimisation, freeing IT to focus on strategic value.
Predictable Cost Structure
Subscriptions replace unpredictable CapEx. With transparent per-user licensing, budgeting is clear—no more hidden server costs.
Enhanced Remote Collaboration
Mobile apps, integrated whiteboards, and seamless integrations empower distributed teams—critical for cross-border projects across the UK, Poland, and West Europe.
The shift to cloud mirrors regional trends. Confluence Cloud GDPR compliance ensures UK and European organisations meet data protection standards. For practical advice and migration playbooks, see

Server vs Data Center vs Cloud Comparison Table

It’s essential to compare Atlassian’s deployment models carefully when planning your migration:
Platform Pros Cons Typical Annual Cost (500 users) Best For
Jira Server • Full control over infrastructure
• Customisable backend
• One-time licence fee		 • End of support February 2024
• High maintenance
• Security updates cease
• No new features		 Variable (infrastructure dependent) Legacy systems requiring immediate migration
Data Center • High availability
• Extended support
• On-premise control		 • 500-user minimum
• Complex infrastructure
• Operational costs
• Limited innovation speed		 ~US$42,000 + infrastructure Large regulated organisations requiring compliance
Atlassian Cloud • Automatic updates
• Disaster recovery
• Scalability
• Mobile-first
• EU data residency		 • Less backend customisation
• Internet dependency
• Subscription model
• App differences		 ~US$35,000 (Standard tier) Most UK, European, and Polish organisations
In short: Server support ends imminently, Data Center carries significant costs, and Cloud emerges as the practical choice for UK and West Europe businesses. For in-depth best practices, review

Migration Preparation & Enterprise Jira Migration Timeline

A structured, phased approach is proven to reduce risk. The six canonical phases:
  • Assess → Plan → Prep → Test → Migrate → Launch

Duration by Organisation Size:

  • Small (<100 users): 8-12 weeks
  • Mid-market (100-1000): 3-6 months
  • Enterprise (1000+): 4-9 months

Phase 1: Assess (2-4 weeks)

Data inventory: Users, licensing, projects, custom fields, marketplace apps, integrations, and data volume. Early discovery = fewer surprises.

Phase 2: Plan (2-3 weeks)

Develop RACI matrix, define KPIs, schedule change-freeze, document rollback, allocate resources, and set communications.

Phase 3: Prep (3-4 weeks)

Provision sandbox, clean up fields/schemes, archive obsolete projects, consolidate workflows, update directories, test authentication.

Phase 4: Test (4-6 weeks)

Multiple dry runs with the Jira/Confluence Cloud Migration Assistants. Resolve blockers, validate data, test workflows/integrations.

Phase 5: Migrate (1-2 weeks)

Production migration during change freeze. Final sync, DNS updates, monitor, validate, and roll back if required.

Phase 6: Launch (2-4 weeks)

Hypercare support: Monitor, track adoption, resolve issues, gather feedback, optimise, and document lessons learned.
Enterprise Jira Migration Timeline Checklist:
  • Executive sponsorship secured
  • Budget approved including contingency
  • Technical team assembled
  • Change management plan documented
  • Training materials prepared
  • Success metrics defined
  • Post-migration support arranged
For technical team structuring and training resources, see DevOps adoption roadmap guide.

 

Budgeting: Using a Jira Cloud Migration Cost Estimator

Accurate budgeting prevents surprises. Major cost drivers include:
  • User Licensing: Tiered pricing—cost per user drops at higher volumes.
  • Marketplace Apps: Cloud equivalents may incur 30%+ license uplift. Assess app availability and alternatives.
  • Data Volumes: Storage grows with attachments, old projects, and retention rules.
  • Downtime Windows: Restricted maintenance may require extra resources, tooling, and overtime.

Use the Jira Cloud migration cost estimator for projections:

  1. Enter current users and apps
  2. Specify data volumes
  3. Select cloud tier
  4. Review PDF cost breakdown
Hidden costs to include:
  • Training and onboarding
  • Extended hypercare IT support
  • Integration/webhook modifications
Users Region Annual Cloud Cost Migration Cost Total First Year
250 UK £21,000 £15,000 £36,000
250 Poland 92,000 PLN 66,000 PLN 158,000 PLN
1000 UK £70,000 £45,000 £115,000

For backup and audit strategy, review backup & Azure DevOps resilience.

 

Step-by-Step Technical Migration Walkthrough

Migration Tools & Preparation:
  • Jira Cloud Migration Assistant (JCMA) – User migration, config, workflows, custom fields
  • Confluence Cloud Migration Assistant (CCMA) – Spaces, attachments, macros, permissions
  • Prerequisite: Atlassian Server 7.13+ or Data Center
Detailed Steps:
  1. Upgrade LTS Version: Update Server to a supported version; verify plugins and run production upgrade
  2. Run Pre-Flight: Audit system, check customisations, assess app compatibility, confirm data integrity
  3. Provision Cloud Sandbox: Register trial, configure authentication, set user groups, enable features, set data residency
  4. Dry-Run Migrations: Start small, document issues, resolve blockers, validate data
  5. Schedule Production: Communicate downtime, freeze changes, prep rollback, assign team roles
  6. Live Migration: Monitor process, address errors, track progress, validate completion
  7. Validation: Automated diff scripts, permission and integration checks, user signoff
Regional Considerations:
  • Polish tax compliance: VAT and audit trails
  • West Europe: Plan cut-over for CET business hours
