Why Migrate to the Cloud?
Before diving into the how, let's address the why. Cloud computing offers compelling benefits for Sydney SMBs:
- Cost efficiency: Replace capital expenditure on servers with predictable monthly operating costs
- Scalability: Add or remove resources as your business needs change
- Remote access: Enable your team to work from anywhere securely
- Disaster recovery: Built-in redundancy protects against data loss
- Automatic updates: Always run the latest, most secure software versions
Phase 1: Assessment and Planning
Inventory Your Current Environment
You can't migrate what you don't know about. Document all applications, servers, storage systems, and their dependencies. Note which applications are critical to business operations and which could be retired.
Assessment Checklist
- List all servers (physical and virtual) and their functions
- Document all applications and their dependencies
- Identify data volumes and growth rates
- Map network configurations and integrations
- Note any compliance or regulatory requirements
- Assess current bandwidth and internet reliability
Choose Your Cloud Strategy
Not everything needs to move to the cloud. Consider these approaches:
- Lift and shift: Move applications as-is to cloud infrastructure. Fastest but may not optimise for cloud benefits.
- Replatform: Make minor adjustments to leverage cloud capabilities. Good balance of speed and optimisation.
- Refactor: Redesign applications for cloud-native operation. Most benefit but highest effort.
- Retire: Decommission applications no longer needed.
- Retain: Keep some systems on-premises where it makes sense (legacy systems, specific compliance needs).
Phase 2: Preparation
Security and Compliance Planning
Cloud security is a shared responsibility. Understand what your cloud provider secures and what remains your responsibility. For Australian businesses, consider data sovereignty—where your data is stored and processed.
Security Preparation Checklist
- Define identity and access management strategy
- Plan multi-factor authentication implementation
- Document data classification and handling requirements
- Review compliance requirements (Privacy Act, industry regulations)
- Plan backup and disaster recovery procedures
- Define security monitoring and incident response processes
Network and Connectivity
Cloud performance depends heavily on your internet connectivity. Assess your current bandwidth, consider redundant connections, and plan for increased traffic during migration.
Phase 3: Migration Execution
Migration Best Practices
- Start small: Migrate non-critical systems first to learn and refine your process
- Migrate in phases: Don't try to move everything at once. Plan logical groupings.
- Test thoroughly: Verify functionality before decommissioning old systems
- Communicate clearly: Keep stakeholders informed of timelines and expected impacts
- Have a rollback plan: Know how to revert if something goes wrong
- Monitor closely: Watch performance and costs closely in the first weeks post-migration
Pro tip: Schedule migrations during low-usage periods and always have your IT support team available during cutover. Weekend migrations often work best for minimising business impact.
Phase 4: Post-Migration Optimisation
Migration isn't the end—it's the beginning. Once you're in the cloud:
- Review and right-size resources based on actual usage
- Implement cost management and alerting
- Enable additional cloud-native security features
- Train users on new systems and processes
- Document your cloud architecture and procedures
- Plan regular reviews of cloud spend and performance

Frequently Asked Questions
How long does a typical cloud migration take?
Timelines vary significantly based on complexity. A simple email migration to Microsoft 365 might take 2-4 weeks. Moving a full server infrastructure to Azure or AWS typically takes 3-6 months for proper planning, execution, and optimisation.
Will cloud computing save us money?
Cloud can reduce costs, but it's not automatic. Benefits come from eliminating hardware maintenance, reducing over-provisioning, and gaining efficiency. However, poorly managed cloud environments can cost more than on-premises. Proper planning and ongoing optimisation are essential.
What about Australian data sovereignty requirements?
Most major cloud providers (Microsoft Azure, AWS, Google Cloud) offer Australian data centres. You can configure your cloud environment to ensure data remains within Australia. For highly regulated industries, verify specific compliance requirements with your provider.
Do we need to migrate everything at once?
Absolutely not. In fact, we recommend against it. A phased approach reduces risk and allows you to learn as you go. Many businesses maintain hybrid environments for years, with some systems in the cloud and others on-premises.
