Zero downtime
Five overnight cutovers; Monday staff logged in to faster systems with no retraining.
Case Study · Cloud / Migration
Helio Health Cloud Move
A regional healthcare provider ran patient systems on aging on-site servers with no failover. We migrated everything to the cloud — zero downtime, full compliance evidence, and a calmer IT team.

The challenge
Critical systems, single point of failure
Scheduling, records, and billing lived on a server stack old enough to vote — no redundancy, backups nobody had tested, and a maintenance window that required closing clinics. One hardware failure away from cancelled appointments.
Any migration had two non-negotiables: patient data protected to healthcare standards, and not a minute of downtime during clinic hours.
The approach
Rehearsed waves, overnight cutovers
We built an encrypted landing zone with private networking, audit logging, and automated backups first. Then we migrated in five rehearsed waves — each practiced on clones, each with a tested rollback, each cut over overnight.
Compliance evidence was generated continuously: encryption proofs, access reviews, and backup-restore drills the auditors could verify independently.
Outcome
Clinics open, systems safer
Verified compliance
Encryption, access, and backup evidence accepted at the next audit without findings.
Recovery in minutes
Tested failover replaced the old cross-your-fingers backup routine.
"Nobody believed a migration could be boring. Cloudmere made it boring — in the best possible way."
