Supported Paths

Enterprise Migration Paths We Deliver

Whether retiring costly legacy licenses, migrating on-premises reporting to Azure, or replacing brittle Excel workbooks, our team executes proven platform transitions.

Excel to Power BI

Transform decentralized spreadsheet models, manual VLOOKUP workflows, and macro-driven workbooks into automated, governed semantic models.

  • Automated scheduled cloud data refreshes
  • Elimination of version conflicts and formula bugs
  • Enterprise Row-Level Security on single dataset

Tableau to Power BI

Consolidate licensing and migrate Tableau Server/Cloud estates. Convert complex LOD expressions (FIXED, INCLUDE, EXCLUDE) into clean, high-performance DAX measures.

  • Precise LOD-to-DAX measure translation
  • Hyper extract conversion into Star Schemas
  • Significant software license cost reduction

SSRS to Power BI

Modernize on-premises SQL Server Reporting Services (SSRS) into interactive Power BI reports and Power BI Paginated Reports (.rdl) in the cloud.

  • Seamless Paginated Report (.rdl) cloud publishing
  • Conversion of static tables to interactive slicing
  • Automated burst email distributions preserved

MicroStrategy to Power BI

Migrate complex MicroStrategy dossiers, schema objects, attributes, and Intelligent Cubes into modern tabular semantic models and Microsoft Fabric Direct Lake.

  • Intelligent Cube to VertiPaq tabular model translation
  • Elimination of complex multi-tiered MicroStrategy servers
  • Native Office 365 and Teams collaboration

On-Premises to Cloud Lakehouse

Migrate legacy data warehouses and on-prem SQL reporting into modern Microsoft Fabric Lakehouses and Databricks with centralized Power BI semantic layers.

  • Automated On-Premises Data Gateway clustering
  • Incremental refresh policies for massive historical data
  • Direct Lake connection to OneLake Delta tables

Cognos & BusinessObjects Modernization

Retire legacy reporting servers. Decouple Universe business layers and report queries into certified Power BI semantic models, reducing maintenance overhead.

  • BusinessObjects Universe (.unx) semantic modeling in DAX
  • Cognos Framework Manager model translation
  • Elimination of end-of-life on-prem software risk
De-risked Execution

Our 4-Phase Migration Methodology

A battle-tested framework engineered to eliminate business disruption, guarantee data fidelity, and accelerate user adoption.

01

Inventory & Rationalization

Scan all existing reports, identify active vs dormant workbooks, and group redundant queries. We establish the migration backlog and prioritize high-value business domains.

Rationalization Matrix
02

Model Modernization & DAX

Instead of copying legacy flaws, we engineer clean Star Schema semantic models. Complex calculations and LOD queries are refactored into optimized DAX measures.

Standardized Semantic Layer
03

Numeric Reconciliation & UAT

Execute side-by-side automated variance tests comparing source legacy outputs to Power BI measures. Validate 100% financial and operational accuracy before user sign-off.

Signed Reconciliation Log
04

Parallel Run & Cutover

Run parallel reporting cycles to build stakeholder confidence. Roll out training, retire legacy infrastructure, and decommission expensive license tiers.

Frequently Asked Migration Questions

Key insights on migration timelines, accuracy validation, and risk management.

We migrate legacy platforms including SAP Crystal Reports, SQL Server Reporting Services (SSRS), Tableau, MicroStrategy, IBM Cognos, SAP BusinessObjects, and unmanaged Excel reporting stacks into modern Microsoft Power BI.
We modernize the underlying data models into Kimball Star Schemas rather than performing fragile 1-to-1 copies. This eliminates redundant queries, consolidates overlapping reports, and ensures high interactive dashboard performance.
We implement automated numeric reconciliations and side-by-side metric audits across source and target systems, ensuring 100% financial and operational accuracy before user acceptance testing.
We conduct structured parallel-run phases where both legacy and Power BI systems run concurrently. We train end users and report consumers on Power BI navigation, slicing, exporting, and mobile access to secure widespread enthusiasm and voluntary adoption.
