Cloud Migration for Australian Small Businesses: How to Move Without Breaking Things
A staged cloud migration plan covering data sovereignty, Microsoft 365 vs Google, and the hidden costs nobody mentions.
Cloud migration projects fail for boring reasons: unclear scope, surprise licensing costs, broken line-of-business apps, and the consultant who left halfway through. Here's the staged approach we use for Australian small businesses to avoid all four.
Stage 1: Discovery (week 1)
Before you move anything, document what you have:
- Every server, what it runs, who depends on it
- Every line-of-business app — vendor, version, supported deployment models
- Data volumes (this drives migration time and bandwidth planning)
- Compliance requirements — especially data sovereignty if you handle health, financial or government data
Australian data sovereignty in 2026
Microsoft 365 and Azure both have Australia-resident options (Australia East / Australia Southeast). Google Workspace data is stored globally with no Australia-only option as of 2026 — fine for most businesses, a dealbreaker for some regulated industries.
Stage 2: Choose your destination
For 90% of Australian SMBs the answer is Microsoft 365 + Azure. The other 10% split is mostly Google Workspace for marketing-heavy businesses and AWS for software companies. Don't pick on price alone — pick on what your team already knows.
Stage 3: Pilot (weeks 2–3)
Move one team — usually 5 users from a non-critical department. Run them on the new environment for two weeks while everyone else stays on the old. This is where you find the broken integrations, the line-of-business app that needs a specific TLS version, the printer that won't authenticate.
Stage 4: Phased rollout
Move teams in waves of 10–20 users per week. Each wave gets:
- A pre-migration data sync (delta sync overnight before cutover)
- A 30-minute Teams session on the morning of cutover
- On-site or floor-walking support for the first half-day
Hidden costs nobody mentions
- Egress fees when moving data between cloud providers — can run to thousands for large datasets
- Storage tier surprises in Azure (hot vs cool vs archive — pick wrong and your backup bill triples)
- Microsoft 365 add-ons like Defender for Endpoint P2, Power BI Pro, audio conferencing — easily another $15/seat/month if you need them
- Bandwidth upgrade at the office — if you're still on a 50/20 NBN plan, plan to upgrade before cutover
- Old server decommissioning — Sophos and Veeam licences often auto-renew if you forget to cancel
Realistic timelines
A 30-user Australian SMB with on-prem file shares, an on-prem accounting server and Exchange on-prem typically takes 6–10 weeks end-to-end. Anyone promising "2 weeks" is either skipping the discovery or planning to skip the testing.
