5 Cloud Migration Mistakes Australian Businesses Make

Moving to the cloud is one of the best decisions a growing business can make. Lower infrastructure costs, better collaboration, access from anywhere: the benefits are well documented. But getting there is where things go wrong.

We have helped dozens of Australian businesses migrate to Microsoft 365 and Azure. The ones that struggle almost always make the same mistakes. Here are the five we see most often, and how to avoid them.

Mistake 1: Moving everything at once

The biggest mistake is treating migration as a single event. Businesses try to move email, files, applications, and phone systems all in one weekend. When something goes wrong, and something always goes wrong, the entire organisation is affected.

What to do instead: Break your migration into phases. Start with something low-risk, like moving a small team's email. Learn from the experience. Adjust your process. Then move the next group.

A phased approach takes longer on paper, but it is faster in practice because you avoid the costly rollbacks and emergency fixes that come with a big-bang migration.

Most of our migrations follow a pattern: email first, then file storage, then collaboration tools, then line-of-business applications. Each phase has its own timeline, testing period, and rollback plan.

Mistake 2: Not auditing licences first

Microsoft 365 has more licence types than most people realise. Business Basic, Business Standard, Business Premium, E3, E5, and a dozen add-ons. Many businesses end up paying for features they will never use because someone picked the wrong plan at the start.

We regularly audit tenants where half the users have E5 licences but only use email and Teams. That is thousands of dollars per year going to waste.

What to do instead: Before you migrate, catalogue what each person actually needs. Do they just need email and basic Office apps? Business Basic or Standard is probably enough. Do they need advanced security, compliance, or analytics? Then Business Premium or E3 might be justified.

Get this right before migration and you will save a significant amount every year. Get it wrong and changing licences later means re-configuring policies, re-assigning features, and potentially disrupting services.

Mistake 3: Skipping user training

Technology only works if people use it. We have seen businesses spend months migrating to SharePoint and Teams, only to find that staff are still emailing attachments to each other because nobody showed them the new way.

This is not a training problem. It is a change management problem. People resist what they do not understand. If your team does not see why the change is happening or how it benefits them, they will find workarounds.

What to do instead: Start communicating before the migration begins. Explain what is changing and why. Run short, practical training sessions focused on the tasks people do every day, not a feature tour of the entire platform.

After migration, provide a simple reference guide and make sure people know where to get help. The first two weeks are critical. If staff get frustrated and develop bad habits early, those habits stick.

Nominate a champion in each department: someone who is a bit more tech-savvy and can answer quick questions for their colleagues. This takes the pressure off your helpdesk and builds internal capability.

Mistake 4: No backup strategy for cloud data

There is a dangerous assumption that because your data is "in the cloud," it is automatically backed up. It is not.

Microsoft 365 has built-in data protection, but it is not a backup. If a user accidentally deletes a SharePoint site, you have a limited recovery window. If a ransomware attack encrypts your OneDrive files and you do not notice for a few weeks, the version history may not go back far enough. If a departing employee deletes their mailbox contents, the data may be gone before you realise.

What to do instead: Implement a third-party backup solution for your Microsoft 365 data. This gives you independent, point-in-time recovery for email, OneDrive, SharePoint, and Teams.

This is not expensive. The cost is typically a few dollars per user per month. But the cost of losing critical business data is enormous.

Your backup strategy should cover:

• Retention: How far back can you restore? Aim for at least 12 months.
• Granularity: Can you restore a single email, a single file, or a single site? Or is it all or nothing?
• Independence: Is the backup stored separately from Microsoft? If your tenant is compromised, your backups should be unaffected.
• Testing: When was the last time you tested a restore? If the answer is "never," your backup strategy is theoretical.

Mistake 5: Treating migration as a one-off project

The migration is done. Everything is in the cloud. Time to move on, right?

Not quite. Cloud environments need ongoing management. Security settings need to be reviewed and updated. New features are released every month. Licences need to be adjusted as people join and leave. Sharing permissions drift over time as people grant access to files and forget about them.

What to do instead: Treat your cloud environment as a living system that needs regular care. Schedule quarterly reviews to check:

• Are security settings still appropriate?
• Are there unused licences you are paying for?
• Are sharing permissions still correct?
• Are there new features that could benefit the business?
• Is your backup still working and tested?

This ongoing management is where a managed IT provider earns their keep. The migration is the beginning, not the end.

Getting the migration right

Cloud migration done well transforms how a business operates. Staff can work from anywhere. Collaboration improves. Costs become predictable. Security gets stronger.

But it takes planning, the right expertise, and ongoing attention. Rushing it or treating it as a tick-box exercise will cost you more than taking the time to do it properly.
