What is Cloud Migration?

Updated April 2026 · 5 min read

Cloud migration is the process of moving your business data, applications, and IT infrastructure from on-premise hardware to cloud-based services. For most small businesses, this means moving email and files to platforms like Microsoft 365 or Google Workspace.

What typically gets migrated

Email from an on-premise Exchange server or legacy email provider to Microsoft 365 or Google
File storage from local servers or NAS drives to SharePoint, OneDrive, or Google Drive
Line-of-business applications from local installations to cloud-hosted versions
On-premise servers to virtual machines hosted in Azure, AWS, or similar platforms

Why businesses migrate to the cloud

The practical benefits for small businesses are real. Cloud platforms handle backup, patching, and availability at a scale that is not practical to replicate with on-premise hardware. Staff can work from anywhere. You stop paying for hardware refresh cycles. And the per-user cost is often less than maintaining equivalent on-premise infrastructure.

The security argument has also shifted. Well-configured cloud environments are typically more secure than the average small business on-premise setup. The qualifier is "well-configured." Default Microsoft 365 settings are not secure settings. Proper migration includes security configuration, not just data transfer.

What a cloud migration actually involves

Discovery and inventory

Cataloging what you have, where it lives, how much data is involved, and what dependencies exist.

Planning and sequencing

Deciding what migrates first, what runs in parallel, and how to handle the cutover without downtime.

Data migration

Moving the actual data, which for large email archives or file shares can take time to complete cleanly.

Configuration and security hardening

Setting up the destination environment correctly before users land on it. This step is frequently skipped and causes most post-migration problems.

User training and cutover

Communicating the change to staff, handling the actual transition, and supporting the first days in the new environment.
