Migration & Modernisation

We run version upgrades, platform moves and SQL Server to PostgreSQL migrations with assessment, rehearsal and a rollback plan, inside a controlled downtime window.

01Problems we solve

What organisations most often face in this area.

  • P.01

    Versions out of support

    Versions no longer patched; an upgrade project postponed every year and growing.

  • P.02

    Unknown compatibility risk

    Nobody knows how the features in use will behave on the new version or target platform.

  • P.03

    Downtime anxiety

    Without knowing how long the cutover takes or whether it can be reversed, no decision is made.

  • P.04

    Licence and cost pressure

    Alternative platforms are on the table, but the application impact has not been measured.

02Migration method

Four phases, a decision gate in each.

No phase starts until the previous phase's output is approved. A way back is defined at every step.

Illustrative example — not real client data

  1. 01

    Assessment

    Inventory, feature usage, dependencies, compatibility risks.

    • Assessment report
    • Risk register

    Method approval

  2. 02

    Planning

    Method, downtime window, rehearsal schedule, validation criteria.

    • Migration plan
    • Rollback plan

    Rehearsal approval

  3. Planned downtime window

    03

    Migration

    Rehearsal in a test environment, then step-by-step execution in the planned window.

    • Rehearsal results
    • Execution log

    Go-live decision

  4. 04

    Validation

    Data integrity, application behaviour and performance comparison.

    • Validation report
    • Hand-over to monitoring

    Close

Rollback path

03Technical scope

Engineering depth.

Upgrade

  • Version upgrades
  • Compatibility level changes
  • Evaluating new version features
  • Post-upgrade performance validation

Relocation

  • Server and hardware moves
  • Data centre moves
  • Consolidation
  • High-availability migration methods

Platform change

  • SQL Server → PostgreSQL assessment
  • Schema and code conversion
  • Data migration and validation
  • Rollback planning

04Value to the organisation

What changes for management.

Controlled downtime

Downtime is measured in rehearsal, not estimated.

A way back

Every step has a defined rollback path.

A current platform

Supported, secure infrastructure that can be maintained.
