A detailed checklist and guide for businesses planning to migrate their operations to the cloud. From assessment to optimization, specifically tailored for Toronto businesses.
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.
