Two Checklists We Use on Real Projects

Condensed from how we plan migrations and ISO 27001 programmes. Use them to sanity-check your own plan.

Cloud Migration Checklist

The eight steps we work through on every migration, whichever cloud you are moving to. Most failed migrations skip step two or step five.

  • Inventory every workload, dependency and data store
  • Classify data and map compliance requirements (PII, PHI, PCI)
  • Choose a migration strategy per workload (rehost, replatform, refactor)
  • Design the target architecture: networking, identity, encryption
  • Set up landing zone, guardrails and cost budgets before migrating
  • Migrate a low-risk pilot first and validate end to end
  • Cut over with a tested rollback plan and monitoring in place
  • Optimise cost and right-size once traffic patterns settle

Go deeper: cloud architecture and migration, infrastructure as code with Terraform, and our FinOps playbook for step eight.

ISO 27001 Readiness Checklist

What actually gets you audit-ready. The certificate is issued by an accredited certification body; these steps get you to the point where that audit goes smoothly.

  • Define ISMS scope precisely (systems, teams, data)
  • Run a gap assessment against Annex A controls
  • Establish a repeatable risk assessment & treatment method
  • Write policies people will actually follow
  • Implement access control, MFA and joiner/mover/leaver processes
  • Stand up logging, monitoring and tested incident response
  • Manage supplier and third-party risk
  • Automate evidence collection for continuous assurance

Go deeper: ISO 27001 readiness guide, ISO 27001 implementation support, and the Radiatus GRC platform for keeping evidence current.

About These Resources

Yes. The guides, glossary, checklists, comparisons and Online Tools are free to read and use, with no email gate.

Yes. They are condensed from how we run cloud migrations and ISO 27001 readiness work. Adapt them to your scope; if you want a second opinion on your plan, ask us.

We add guides when we have something practical to say from real engagements, rather than on a fixed schedule. The blog lists everything, newest first.
