Many organizations move to Power BI because they already pay for Microsoft 365, want lower BI licensing costs, or need reporting that fits better with Azure and Fabric. The move itself is where things get risky: hundreds of reports, calculations that behave differently between tools, users attached to their old dashboards, and numbers that must match exactly on day one.
Our Power BI migration services move your reports from Tableau, Qlik, SSRS, Crystal Reports, Excel, or Looker into Power BI — rebuilt properly with a clean data model, validated number by number, and rolled out with training so users switch with confidence.
What are Power BI migration services? Power BI migration services move reports, dashboards, data sources, and business logic from other BI and reporting tools — such as Tableau, Qlik Sense, QlikView, SSRS, Crystal Reports, Looker, or Excel — into Microsoft Power BI. The work includes inventorying and rationalizing existing reports, redesigning data models, converting calculations to DAX, rebuilding visuals, validating results against the old system, setting up security and refresh, and training users.
Power BI Migration at a Glance
Question | Answer |
|---|---|
What it is | Moving reports and BI logic from other tools into Power BI |
Migrate from | Tableau, Qlik Sense, QlikView, SSRS, Crystal Reports, Looker, Excel, legacy reporting tools |
Core deliverables | Report inventory, rationalization plan, Power BI semantic models, DAX measures, rebuilt reports, validation reports, security, training |
Approach | Inventory, rationalize, rebuild on shared models, validate, roll out in waves |
Typical timeline | A small set of reports in a few weeks; larger estates in waves |
Engagement models | Migration assessment, migration project, post-migration optimization and support |
Why Companies Migrate to Power BI
Licensing cost. Power BI is often included in or cheaper alongside existing Microsoft agreements.
Microsoft ecosystem fit. Tight integration with Microsoft 365, Teams, Excel, Azure, and Fabric.
Consolidation. Several BI tools replaced with one standard platform.
Governed semantic models. Shared datasets reduce duplicated logic across reports.
Legacy tools reaching end of life. Older reporting servers are hard to maintain.
What Changes Between Tools
Area | Typical source behavior | In Power BI |
|---|---|---|
Calculations | Tableau calculated fields and LOD expressions, Qlik set analysis, SQL in SSRS | DAX measures and calculated columns |
Data model | Often one data source per workbook or app | Shared star-schema semantic models |
Data preparation | Tableau Prep, Qlik load scripts, SQL | Power Query, dataflows, or the data warehouse |
Security | Tool-specific user filters and permissions | Row-level security and workspace roles |
Distribution | Server sites, subscriptions, email | Workspaces, apps, subscriptions, Teams |
Because logic works differently, we rebuild rather than convert reports line by line — and validate that the numbers still match.
Our Power BI Migration Services
Report inventory and usage review
We list every report, data source, calculation, and user group, and check which reports are actually used.
Rationalization
We identify duplicate, overlapping, and unused reports, so you migrate fewer, better reports instead of copying clutter.
Semantic model design
We design shared Power BI semantic models so many reports reuse the same tested logic.
Calculation conversion
We translate Tableau, Qlik, SSRS, and Excel logic into DAX and Power Query, documenting each conversion.
Report rebuild
We rebuild reports to Power BI design standards, preserving what users rely on and improving where it helps.
Validation
We compare totals, filters, and edge cases between old and new reports and resolve every difference before sign-off.
Security and refresh
We set up row-level security, workspaces, gateways, and scheduled refresh.
Rollout and training
We migrate in waves, run old and new reports in parallel for a short period, and train viewers and report builders.
How It Works
Step 1: Assess
We inventory reports, sources, logic, and usage.
Step 2: Plan
We rationalize the report list and group migration into waves.
Step 3: Model
We build shared semantic models for each wave.
Step 4: Rebuild
We rebuild reports and convert logic to DAX.
Step 5: Validate
We compare results with the old tool and fix every difference.
Step 6: Roll out
We publish, train users, run in parallel, and retire old reports.
What You Get
A full report inventory and rationalization plan
Shared, documented Power BI semantic models
Rebuilt, validated reports
Security, refresh, and workspace setup
Training for viewers and report builders
A retirement plan for the old tool
Who This Is For
Tableau and Qlik users | SSRS and Crystal Reports users | Excel-based reporting teams | Companies consolidating BI tools |
|---|---|---|---|
Moving to Power BI to reduce cost or standardize on Microsoft | Modernizing ageing reporting servers | Replacing spreadsheet reports with interactive dashboards | Standardizing several tools onto one platform |
Why Work With Codersarts
Migrations fail when they copy reports one by one without fixing the logic underneath. We rationalize first, build shared semantic models, validate every number, and roll out in waves with training. Our Power BI consulting team also optimizes reports after migration, and our Tableau consultants understand the source logic you're moving from.
Frequently Asked Questions
Can Tableau reports be converted automatically to Power BI?
Not reliably. The tools model data and calculations differently, so reports should be rebuilt on a proper Power BI model. Tools can help inventory and document existing reports.
How long does a Power BI migration take?
A small set of reports can move in a few weeks. Larger report estates are migrated in waves over several weeks or months, depending on the number and complexity of reports.
How much does Power BI migration cost?
Cost depends on the number of reports, the complexity of logic, data sources, and security requirements. An assessment produces a fixed quote for each migration wave.
How do you make sure numbers match?
We compare totals and filtered results between old and new reports, test edge cases, and resolve every difference before users switch.
Will our users accept the new reports?
We involve key users early, keep familiar layouts where they matter, run old and new reports in parallel briefly, and provide training.
Should we migrate every report?
Usually not. Many organizations find a large share of reports are unused or duplicated. Rationalizing first saves time and leaves a cleaner Power BI environment.
Can you migrate Excel reports to Power BI?
Yes. We rebuild spreadsheet reports on proper data sources with automated refresh. For moving spreadsheet data itself into a database, see Excel to database migration.
