A successful cloud migration moves your business systems to a more flexible, cost-efficient platform without losing data, access, or productivity along the way. For most Saskatoon small and mid-sized businesses, the question is not whether to migrate but whether you are prepared to do it without disrupting daily operations. This checklist walks through what readiness actually looks like, step by step.
We have guided enough Saskatchewan businesses through cloud migrations to know that the planning phase determines the outcome. Skip it and you will spend weeks untangling email routing errors and missing shared files. Get it right and your staff may not even notice the cutover happened.
Key Takeaways:
- Start with a full inventory of your current systems, applications, and data storage before planning any migration
- Not every workload belongs in the cloud, so evaluate each system individually rather than migrating everything at once
- Test the migration on a small scale before the full cutover, and always have a rollback plan
- Security configuration in the cloud differs from on-premises, so access controls and backup strategies need to be redesigned, not copied
- A local Saskatoon IT partner can be on-site during the cutover, which phone-based national providers cannot do
What Does Cloud Migration Actually Involve?
Cloud migration is the process of moving business applications, data, and IT services from on-premises servers or local workstations to cloud-hosted platforms. For Saskatoon businesses, the most common migrations involve Microsoft 365 for email and documents, hosted servers for line-of-business applications, and cloud backup solutions replacing tape or local drive backups.
One mistake we often see is businesses treating cloud migration as a single event rather than a phased project. Each system has its own dependencies, user access requirements, and integration points. Moving email without updating the DNS records correctly will cause bounce-backs. Moving a shared drive without preserving folder permissions will create access chaos. The migration needs to be sequenced, tested, and verified system by system.
Common mistake: Migrating to the cloud over a weekend with no testing on Friday and no rollback plan on Monday. If something breaks, your staff starts the week unable to work and there is no quick way back.
Step 1: Inventory Your Current Systems
Before anything moves, you need a complete picture of what exists. This means documenting every server, application, storage location, user account, and integration point in your current environment. We have found that many Saskatoon businesses cannot produce this inventory off the top of their head because their systems were built incrementally over years, with different people making different additions.
A proper inventory includes: server names and functions, operating systems and versions, installed applications, data storage locations and sizes, user accounts and access levels, external integrations (payment processors, CRM connections, accounting software links), and backup configurations. If you do not have this documentation, your IT provider should create it as the first deliverable of the migration project.
Expert Tip: If your current IT provider cannot produce a system inventory within a reasonable timeframe, that itself is a migration risk. You cannot safely move what has not been documented.
Step 2: Assess Which Systems Should Move and Which Should Stay
Not every system benefits from cloud hosting. Some legacy applications run better on local servers, either because they require low-latency connections to on-site hardware or because the vendor does not support cloud deployment. The assessment phase evaluates each system against criteria that matter for your business.
| System Type | Cloud Suitability | Typical Recommendation |
| Email and calendar | High | Migrate to Microsoft 365 or Google Workspace |
| File storage and shared drives | High | Migrate to SharePoint, OneDrive, or cloud file platform |
| Line-of-business apps | Medium | Depends on vendor cloud support and integration needs |
| Legacy on-premises apps | Low | May remain on local server or require replacement |
| Backup and disaster recovery | High | Move to cloud backup with verified restore testing |
We have found that the systems most Saskatoon businesses want to move first – email and file storage – are also the ones with the clearest cloud benefits: lower maintenance costs, built-in redundancy, and access from anywhere. The systems that require more deliberation are specialized applications, typically industry-specific software that may have limited cloud hosting options or vendor restrictions.
Step 3: Plan Your Data Transfer Strategy
How data moves to the cloud matters as much as what moves. For large datasets, a direct internet transfer may take days or fail partway through. For email migrations, the sequence of mailbox moves affects which features are available during the transition period. Your IT provider should present a transfer plan that accounts for data volume, bandwidth, business hours, and acceptable downtime windows.
In our experience, the best migration approach is a staged cutover. Move a small test group first, verify that email routing, file access, and application functionality all work correctly, then migrate the remaining users in batches. This way, if something breaks, it affects a small number of people for a short time rather than the entire organization simultaneously.
Common mistake: Migrating all users at once because it seems faster. When the migration affects 40 people instead of 5, the support burden is 8 times higher and the rollback window is far more painful.
Step 4: Redesign Security for the Cloud — Do Not Copy It
Cloud security works differently from on-premises security. Your firewall protected the perimeter of your local network, but in the cloud, your data lives on infrastructure you do not physically control. Access management becomes the primary security boundary, which means multi-factor authentication, conditional access policies, and identity management need to be configured before users start working in the new environment.
We recommend treating the migration as an opportunity to improve your security posture rather than simply replicating what you had. Many Saskatoon businesses we work with were running with outdated password policies and no multi-factor authentication on their local servers. Moving to the cloud is the natural moment to enforce stronger controls because the platform supports them natively.
Our cybersecurity services can help design the security architecture for your cloud environment, and our network security expertise covers the connection between your office network and cloud resources.
Step 5: Verify Backups Before, During, and After Migration
Backups are your safety net throughout the migration. Before the migration, take a full backup of every system being moved. During the migration, maintain the original systems in a read-only state so that data cannot be accidentally modified while the transfer is underway. After the migration, test a restore from the new cloud backup to confirm it works.
One pattern we have seen repeatedly is businesses assuming that cloud platforms handle backups automatically. Microsoft 365, for example, has some built-in recovery features, but they are not a substitute for a proper third-party backup. Deleted emails, overwritten files, and malicious data destruction can all result in permanent data loss if you rely solely on the platform’s native retention.
Expert Tip: Test a restore from your cloud backup within the first week after migration. Do not wait until you actually need to recover something to discover the backup was not configured correctly.
Step 6: Plan Post-Migration Testing and User Communication
The technical migration is only half the project. The other half is making sure your staff can actually work in the new environment. Users need to know how to access their email, where shared files now live, how to set up multi-factor authentication, and what to do if something looks different or does not work as expected.
We have found that a brief user guide — even a single page — dramatically reduces post-migration support calls. Cover the essentials: how to log in, where files are stored, how to set up the authenticator app, and who to call if something is not working. Our IT helpdesk services provide post-migration support so that user questions are handled by a team that knows the migration context, not a generic support line.
Cloud Migration Readiness Checklist

- Rollback plan documented: steps to revert if the migration encounters critical issues
- User communication prepared: login instructions, file locations, and support contact shared with staff
- Post-migration testing scheduled: functionality checks for email, files, applications, and integrations
- Support team briefed: helpdesk has migration context and can resolve user issues quickly
What We’d Recommend for Saskatoon Businesses
If this were your business, we would not migrate everything at once. Start with email and file storage, which have the clearest benefits and the lowest risk, then evaluate line-of-business applications after the core migration is stable. We would also insist on a local IT partner who can be on-site during the cutover rather than a phone-based provider who cannot physically see what is happening in the office.

Frequently Asked Questions
How long does a cloud migration take for a small business?
For a typical Saskatoon SMB with 10 to 30 users, email and file migration usually takes 2 to 4 weeks including planning, testing, and cutover. More complex environments take longer.
Will my staff experience downtime during the migration?
With a staged approach, downtime is minimal, typically a few hours per user group during off-hours. Your IT provider should schedule cutovers outside business hours.
Do I still need on-premises servers after migrating to the cloud?
It depends on your applications. Many businesses eliminate on-premises servers entirely, but those running specialized software may keep one local server for specific workloads.
Is cloud migration expensive for a small business?
Monthly cloud subscription costs are often lower than the combined cost of server hardware, electricity, maintenance, and replacement cycles. The migration project itself is a one-time investment.
What happens if the migration goes wrong?
A proper migration plan includes a rollback strategy. If critical issues arise during cutover, systems can be reverted to the pre-migration state while problems are resolved.
Can I migrate to the cloud without an IT provider?
Small, simple migrations can be self-managed, but most Saskatoon businesses benefit from professional support to avoid data loss, security gaps, and extended downtime.
Does cloud migration improve my security?
It can, if security is configured correctly during the migration. Cloud platforms offer multi-factor authentication and conditional access features that many on-premises setups lack.
