An aging network, migrated
Planned and executed a datacenter-to-cloud migration that included full mailbox and identity conversions from on-prem Active Directory & Exchange to Azure & M365 hosting with 0 downtime. Cut spend and tightened security at the same time. Not a lift-and-shift, but a deliberate re-architecture.
Challenge
Aging on-premises hardware was nearing end-of-life and a "just move it to the cloud" plan was on the table...the kind that doubles costs and ports every old weakness along with the workload. Leadership needed the move to reduce both risk and spend, not trade one problem for two.
Approach
I designed a landing-zone architecture first including identity, network segmentation, and policy guardrails. Then selected tooling to support the migration of all user identities and their associated mailboxes in pre-scheduled waves, right-sizing and re-platforming where it paid off instead of cloning the old footprint. Cost controls and security baselines were built in from day one.
Outcome
The firm retired its aging hardware, reduced its run-rate meaningfully, and came out with a stronger security posture than it went in with. One that allowed for segmention, proper governance, and full network observability.
