Cloud migration

Tenant-to-tenant Azure migration

Planned the infrastructure side of a large Azure migration across application services, databases, secrets, storage, networking, and DevOps workflows.

Proof block

What this proves

A compact hiring view of the work before the deeper project narrative.

Problem

A cloud platform needed to move across tenant boundaries without turning every dependency into one fragile cutover.

My ownership

Owned the infrastructure planning model, resource classification, migration sequencing, and unblock work for dependent teams.

Result

Created a reusable tenant migration playbook that reduced cutover risk and kept development work moving.

Transferable skill

Can turn a large ambiguous cloud move into an owned resource matrix, dependency plan, and validation story.

Situation

The platform needed to move from one Azure tenant boundary to another without turning the cutover into a single high-risk event.

Role

Owned the infrastructure planning model, resource classification, migration sequencing, and unblock work for dependent development teams.

Actions

  • Built a resource matrix that classified each service by migration path: handover, redeploy, export/import, rebuild, or scripted copy.
  • Created reusable PowerShell and AzCopy patterns for safe storage movement across tenant and subscription boundaries.
  • Recreated platform foundations in the destination environment, including DevOps integration, secrets handling, and application observability.
  • Resolved private connectivity issues by tracing name resolution, private endpoint behavior, and certificate identity expectations.

Outcomes

  • Reduced cutover risk by replicating the data tier before final handover.
  • Turned one migration into a reusable playbook for future cloud moves.
  • Helped the development team keep momentum while infrastructure ownership changed underneath the platform.

Public safety

What is preserved

The project details are intentionally sanitized for a public repository while keeping the operating logic and technical tradeoffs visible.

Architecture thinking

Resource categories, dependency order, validation habits, and operational tradeoffs remain visible.

Impact

The outcomes focus on risk reduction, repeatability, cost awareness, and stakeholder alignment.

Protected details

Internal hostnames, ticket identifiers, raw IPs, client names, and sensitive names are excluded.
