Less complexity. Same numbers.Ready for AI agents.

Your data platform was built to inform people. But to get the most out of AI agents, you need a data platform that allows AI to actually use data and perform tasks. Leave Teradata, Netezza, Oracle, SQL Server or Synapse, or redesign the Microsoft Fabric, Databricks or Snowflake platform you already run, up to 4–5× faster than a manual rewrite, at around half the cost.

What modernization should deliver

01

Lower the cost of running data

Retire unused tables, pipelines and reports, cut compute and simplify maintenance, instead of paying to move them.

02

Make engineering faster

Reusable architecture, automation and AI-assisted engineering, so a new source or KPI takes days, not a project.

03

Keep every number trusted

Validated business rules, consistent models and reconciliation, so finance and operations see the same figures on the old and new platform.

04

Give AI agents the context they need

Governed definitions, relationships and access, so Copilot, Genie, Cortex and your own agents can act on the data, not just query it.

In short

Data Semantics helps businesses modernize their data platforms by migrating legacy systems to modern platforms such as Microsoft Fabric, Databricks and Snowflake, or optimizing existing ones. Using AI to automate code conversion, fixes, validation and reconciliation, we deliver modernization faster than a manual rewrite, and at around half the cost. We also transform existing business logic into knowledge graphs and structured context, making enterprise data ready for AI agents to do more than generate reports and actually take action.

Why modernize now

Your data platform was built to inform people. AI agents need it to act.

Moving to Fabric, Databricks or Snowflake modernizes the technology. Most platforms still carry a dashboard-era design: meaning hidden in report formulas, nightly loads, access set up for people and output that ends in a chart. That works for people reading reports. It breaks when an agent has to decide and act.

What we modernize

Modernize what you need. Keep what already works.

Some teams need to leave legacy technology; others need to get more from a cloud platform they already run. Warehouses, pipelines and reports usually move together, so the same rules, models and tests carry through from source to report.

Warehouses

Data Warehouse & Lakehouse Modernization

Data Warehouse Modernization moves a legacy warehouse onto a modern lakehouse or cloud warehouse, with the business logic carried over, cleaned up and proven equal, including industry data models such as Teradata FSLDM.

  • Teradata, Netezza, Oracle and Exadata, SQL Server, Azure Synapse, SAP BW, Hadoop
  • Thousands of objects inventoried and ranked by usage
  • Stored procedures rebuilt as modern pipelines, in a medallion architecture
  • Phased cutover by subject area, with old-versus-new parity
AI-assisted with DataPrep 360
Pipelines

ETL & Pipeline Modernization

ETL & Pipeline Modernization rebuilds ageing ETL jobs as tested, monitored pipelines that are cheaper to run and easier to change.

  • SSIS, Informatica, ODI, DataStage, Talend and legacy Data Factory jobs
  • PySpark, Spark SQL, dbt or Fabric pipelines
  • Automated tests and data quality checks
  • Batch and near-real-time loads
AI-assisted with DataPrep 360
Reporting

Report & Semantic Model Migration

Report & Semantic Model Migration moves reporting onto governed semantic models in Power BI and Fabric, and retires the reports nobody uses.

  • Cognos, Business Objects, OBIEE, MicroStrategy, Tableau and SSRS
  • Report usage analysis and rationalisation
  • One governed semantic model per domain
  • Old-versus-new report comparisons
AI-assisted with DataPrep 360
Already on a modern platform

Make Your Modern Platform Agent-Ready

Already on Fabric, Databricks or Snowflake? You have modern technology. Now give it a design AI agents can act on, usually without another migration.

  • Semantic layer and ontology, built from your existing models and measures
  • Fresher data where decisions need it
  • Governed write-back to your ERP and CRM, so agents can act, not just answer
  • Agent access policies, lineage and continuous quality monitoring
  • Plus cost, performance and pipeline optimization

How AI does the work

AI reads the old estate and drafts the new one. Engineers prove it.

AI takes on the slow, manual work that makes platform migrations drag on, so you run two platforms for weeks, not years. Our engineers review every output and your data owners approve every rule. Target modeling, code generation and data quality checks run in DataPrep 360 today. Architects own the design, engineers review every generated object and business owners validate the critical calculations.

  • Estate inventory

    AI scans every table, pipeline, procedure and report in the old platform, with usage, and flags what nobody uses any more.

    You get: a move, fix or retire list

    Checked by: your data owners decide what moves

  • Rule extraction

    AI reads legacy SQL, ETL and report logic and writes each business rule out in plain language, with its source.

    You get: a plain-language rule catalog

    Checked by: architects verify each rule against the source

  • Code conversion

    AI drafts Spark SQL, PySpark, dbt or Fabric pipeline versions of legacy procedures and ETL jobs.

    You get: converted code in your repository

    Checked by: engineers review and test every object

    Runs in DataPrep 360 →
  • Target modeling

    Medallion layers and dimensional models are proposed from the extracted rules and source tables.

    You get: a documented target design

    Checked by: architects approve the design

    Runs in DataPrep 360 →
  • Failure triage

    When a pipeline or test fails, AI reads the error and proposes the fix.

    You get: fewer stalled builds

    Checked by: an engineer approves every fix

  • Parity checks

    Old and new outputs are compared, from tables and KPIs to full reports, and every difference is explained.

    You get: a parity report per domain

    Checked by: data owners sign off before switch-over

Always in controlOwner approval for every ruleTested before every releaseEvery change on record
Speed with control

Same numbers, or a reason why.

Moving fast only helps if leadership trusts the new numbers. Every rule we extract and rebuild sits in a decision record: what the old platform did, what the new one does, who approved it and why. So every difference at parity is either a defect to fix or an improvement someone signed off.

Same numbers where business rules are unchanged. Explained and approved differences where improvement is intended.
From legacy object to proven parity AI extracts the rule from a legacy object, an owner decides to keep, fix or retire it, AI rebuilds it on the new platform, and AI parity checks explain every difference as either a defect to fix or an approved improvement. The decision record runs alongside every step.

Simplified view. AI does the work; people make the decisions; the record links them.
  • Logic understood, not copied

    Legacy rules are written out in plain language before they're rebuilt, so you don't carry years of workarounds onto a new platform.

  • Retire with confidence

    Usage data shows which tables, jobs and reports nobody touches. Retiring them cuts migration effort and running cost.

  • Parity proven, domain by domain

    Old and new outputs are compared after every build, so each domain can switch over as soon as it's proven, not at one big-bang date.

  • Moved progressively, not big-bang

    Workloads move by business domain or release wave, with old and new run in parallel only until each domain is signed off.

Ready for AI agents

Your old platform's logic becomes the context your AI agents run on.

An ontology is a shared model of your business: the customers, products, orders, contracts and KPIs, how they relate, and which system each comes from. Most migrations throw the old platform's logic away and rewrite it. We extract it, have it approved, and turn it into the semantic layer, knowledge graph and context graph your reports and AI agents run on, ready for Fabric IQ, Copilot, Databricks Genie, Snowflake Cortex or your own agents. That is what lets the new platform do what the old one never could: let agents act on your data, not just report on it.

Customerone definition ProductOrderInvoiceNet revenueContractAccount ownerERP · gold layerERP · lakehouseERPsemantic model KPICRMCRM
Simplified view. Your ontology is modeled on your own entities, definitions and systems.
  • Rules become definitions

    Every rule we extract from legacy code becomes a governed definition, so "net revenue" or "active customer" means one thing everywhere.

  • Built into the new platform

    The ontology sits in the semantic layer of Fabric, Databricks or Snowflake, not in a separate tool you have to maintain.

  • Agents with context

    AI agents and copilots know what each table means, how it connects and which policies apply, so their answers can be trusted.

  • Built once, reused

    The same model serves Power BI, decision intelligence and AI agents, and the next domain you migrate.

Frequently asked questions

Choosing a path

We’re already on Fabric or Databricks. Why would we modernize again?

Because most modern platforms still carry a dashboard-era design: business meaning hidden in report measures, nightly loads, access set up for people and output that ends in a chart. Data Semantics redesigns the platform for AI agents to act, with shared business meaning in an ontology, data as fresh as decisions need, per-agent access, governed write-back to your systems and continuous quality monitoring. This usually needs no new migration.

Should we move to Microsoft Fabric, Databricks or Snowflake?

It depends on your existing estate, skills and AI plans. Fabric suits organizations standardized on Microsoft and Power BI. Databricks suits heavy data engineering and machine learning. Snowflake suits multi-cloud data sharing and SQL-first teams. We deliver on all three and help you choose before you commit.

Is modernization necessary before implementing enterprise AI?

Not always. Many AI use cases can start with targeted integration, data quality fixes, a semantic model and governed access to the systems you have. We modernize the part of the foundation the use case needs, rather than rebuilding everything first.

How it works

How do you prove the new platform gives the same numbers?

Automated parity checks compare old and new outputs at every level, from row counts and totals to KPIs and full reports, after every build. Each difference is traced to a defect to fix or a deliberate improvement that a business owner approved.

How do you prevent legacy technical debt from moving to the new platform?

Data Semantics assess usage, dependencies, business rules and design before anything moves. Objects nobody uses are retired, outdated patterns are redesigned, and critical calculations are carried over through documented, approved validation, so the new platform starts clean.

Migration routes

How do we move from Azure Synapse to Microsoft Fabric?

Inventory the Synapse workloads, decide what moves, what changes and what retires, then rebuild SQL pools, pipelines and notebooks in Fabric and move the Power BI semantic models alongside. We prove parity between old and new before switching Synapse off.

Timeline and cost

How long does a data platform modernization take?

A typical Data Semantics program takes 3 to 4 months after the assessment, moving one subject area at a time. Larger estates are phased by domain, so each part goes live as soon as its numbers are proven.

Can we run the old and new platforms in parallel?

Yes, for as short a time as possible. Each subject area runs on both platforms only until parity is proven and signed off, then the old version is switched off, so you avoid paying for two platforms for years.

What is the Data Platform Assessment?

The Data Platform Assessment is Data Semantics’ fixed-price review of your current platform: architecture and workload inventory with usage, dependencies and technical debt, pipeline reliability, data quality and reconciliation gaps, cost and performance opportunities, and AI readiness. You get recommended priorities, an indicative investment and a roadmap, whether the target is Fabric, Databricks, Snowflake or the platform you already run.

How is a modernization priced?

It starts with the fixed-price Data Platform Assessment, which inventories your estate and gives you a costed plan. The program is then priced against that plan, so you know the cost before committing to the move.

Start the conversation

Your next data platform investment should simplify the business, not add another layer.

Whether you’re leaving a legacy warehouse, want to get more from modern platforms, or preparing your data for AI agents, we’ll show you the practical path, with the numbers to back it.
