Cloud Migration Planning for Toronto Businesses
Cloud migration moves your infrastructure, applications, and data from on-premises hardware to cloud platforms like Microsoft Azure, Microsoft 365, or AWS. A structured checklist prevents common migration failures: data loss, unexpected downtime, cost overruns, and security gaps that open during the transition.
Pre-Migration Assessment Checklist
- Inventory all applications and dependencies: Document every application, its dependencies, and which users rely on it before moving anything.
- Classify data by sensitivity: Identify regulated data (patient records, legal files, financial data) that has compliance implications for cloud storage location.
- Assess current network bandwidth: Cloud workloads increase internet dependency. Confirm your connectivity supports expected cloud traffic before migrating.
- Define RTO and RPO targets: Agree on acceptable downtime and data loss tolerances for each application before migration.
- Identify licensing implications: On-premises licenses often don't transfer to cloud. Budget for cloud subscription costs before starting.
Migration Execution Checklist
- Validate backups before any migration step
- Migrate in phases - non-critical systems first to test the process
- Run parallel environments during cutover to reduce rollback risk
- Test application performance and user access in the cloud before decommissioning on-premises
- Update firewall rules, DNS records, and security policies for cloud architecture
Post-Migration Optimization
Migration is not the end of the process. After moving to the cloud, optimize resource sizing to avoid paying for unused capacity, configure auto-scaling, implement cloud security posture management, and establish ongoing cost monitoring.
