    CLOUD MIGRATION

    Migrate with Minimal Downtime

    Move applications, data, and infrastructure to AWS, Azure, or Google Cloud with dependency mapping, validated data transfer, and planned cutovers that keep your business running.

    How we approach a cloud migration

    Migration Paths
    7Rs

    Rehost, replatform, refactor, and more, chosen per workload rather than one-size-fits-all.

    Cutover Waves
    Phased

    Workloads move in planned waves, with rollback procedures ready at every cutover.

    Data Integrity
    Verified

    Replication and validation checks before and after every cutover.

    Moving workloads in planned, reversible waves

    Each application is assessed, matched to a migration path, and moved in a planned wave, with validation and a rollback plan at every cutover.

    Seamless Cutover

    Minimal-downtime migration strategies for mission-critical applications.

    Workload Optimization

    Right-sizing resources during migration to prevent over-provisioning costs.

    Security in Transit

    End-to-end encryption and validation for all data moving to the cloud.

    Migration Activities

    01

    Workload Discovery

    Catalog applications and map dependencies across your entire on-premise environment.

    02

    Readiness Assessment

    Decide which applications suit cloud-native redesign and which fit a lift-and-shift move.

    03

    Data Replication

    Run secure, throttled data transfers that avoid network congestion during migration.

    04

    Validation & Testing

    Test application functionality and performance in the target environment before cutover.

    05

    Cutover Planning

    Coordinate DNS, database, and traffic switches with rollback procedures and planned windows.

    06

    Post-Migration Review

    Verify performance, security posture, and cost immediately after go-live.

    Migration scenarios by industry

    Examples of the systems and data that are typically moved to the cloud in each industry.

    Move clinical and administrative systems while keeping patient data intact.

    Inventory of clinical applications and their interfaces before anything moves.
    Encrypted record transfer with an audit log for each batch.
    Rehosting of scheduling and billing systems in low-activity windows.
    Image archive transfer with checksum comparison against the source.
    Parallel run of patient portals before the DNS switch.
