Fabric migration, Power BI and capacity operations

Fabric Migration & Power BI Optimisation

Move data and reporting to Microsoft Fabric without losing business meaning. Then improve the Power BI estate and operate capacity around measured demand.

A migration is finished when the business can trust and run the new system.

Moving tables is only part of the job. Measures, reports, permissions, refreshes and support arrangements also have to survive the move. We validate the old and new paths side by side before cutover.

More than 10 migrations delivered to Microsoft Fabric, mainly from Snowflake, Azure Synapse, Azure SQL and on-premises SQL Server.

Core service capabilities

Microsoft Fabric, Power BI & capacity operations

Migration discovery & target design

Inventory warehouse structures, transformations, reports, semantic models and the business processes that depend on them.

Fabric migration & controlled cutover

Move data and reporting in manageable stages, reconcile the new path and agree acceptance, rollback and handover.

Power BI estate optimisation

Improve tenant and workspace design, semantic models, DAX, report behaviour and refresh reliability without separating performance from governance.

Fabric capacity optimisation

Connect utilisation, workload windows and service constraints to capacity sizing, scheduling, autoscaling policy and cost scenarios.

Workload & refresh tuning

Investigate queries, processing patterns, job overlap and refresh design before treating more capacity as the answer.

Monitoring & operating review

Track why performance or capacity changed, observe the result and compare the estate with the agreed baseline.

Discovery, delivery and handover

Establish the workload case

Map sources, transformations, semantic models, reports, identities, schedules and the business cycles that cannot be disrupted. The assessment can conclude that some workloads should stay where they are.

Design the target and the controls

Agree data layers, workspace boundaries, ownership, security, deployment paths and capacity assumptions before rebuilding the estate.

Build and reconcile in stages

Keep the existing path available while records, balances, measures, report behaviour and access are compared against agreed acceptance checks.

Cut over, hand over and observe

Agree rollback and support ownership, then tune refreshes, queries and capacity using evidence from real operation rather than design-time assumptions.

Our methodology

  1. 01DiscoverAgree the outcome, the decisions and the requirements.
  2. 02Current stateMap how the work and data flow today, with evidence.
  3. 03Root causesFind what drives the delay, rework or disagreeing numbers.
  4. 04ApproachAgree the target design, scope and measures of success.
  5. 05BuildBuild the data model and reports on the agreed design.
  6. 06OptimiseTest at real volumes; tune speed, cost and usability.
  7. 07ProductioniseRelease with managed deployment, monitoring and support.
  8. 08GovernSet owners, access and controls so it keeps working.
Swimlane process map: To-be: per-workload cutover with acceptance and rollback. The steps are listed below the diagram.
Process redesignTo-be: per-workload cutover with acceptance and rollback Cutover is a governed decision: every check type passes, business acceptance is recorded, and a rollback owner and window are agreed before switching consumers.

Lanes: Migration team, Data owner, Business acceptance, Steering / CAB.

  • Workload rebuilt
  • Parallel run + reconcile
  • All checks pass?
  • Explain / fix variance
  • Acceptance test: reports + access
  • Approve cutover + rollback owner
  • Switch consumers, freeze legacy
  • Hypercare window
  • Legacy retired
Architecture diagram: Staged migration with a parallel run and reconciliation. The components are listed below the diagram.
Reference architectureStaged migration with a parallel run and reconciliation The legacy path stays live while Fabric is built and reconciled in stages. Cutover is per workload, with rollback ownership agreed. Capacity Metrics and workspace monitoring then feed the operate-and-optimise loop.
Components in this design
  • Azure Synapse (dedicated SQL pool)
  • SQL Server (on-prem / Azure SQL)
  • Snowflake (cloud warehouse)
  • Mirroring (keep in sync in parallel)
  • Copy job / pipelines (history + increments)
  • Fabric warehouse (rebuilt model)
  • New semantic model (Direct Lake)
  • Legacy model (kept until cutover)
  • Reconciliation (records, balances, measures)
  • Readiness report (sample report on this page)
  • Capacity Metrics (CU, throttling)
  • Capacity policy (resize within bounds)

Delivery: interactive Power BI sample reportFabric Migration & Estate Operations Track migration waves and show, per workload, whether records, balances, measures, report behaviour and access match between the legacy and Fabric paths. Delivered with named owners, role-based access, release pipelines and a controlled way to change governed measures.
