Many businesses still run on a data setup built a decade ago: an on-premise warehouse, nightly batch jobs written in tools nobody wants to maintain, reports built in spreadsheets on top, and data that takes a day or more to reach anyone who needs it. It still works — just barely — but every new request is slow, expensive, and risky.
Data modernization replaces that with a modern data platform: cloud-based, automated, governed, and ready for analytics and AI. It's not one big switch. Done well, it's a planned sequence of improvements that delivers value at each step while the business keeps running.
Our data modernization services cover the full journey — assessment, target architecture, migration, pipelines, governance, and AI readiness — so you end up with a platform built for the next ten years, not just a newer copy of the last one.
What are data modernization services? Data modernization services move an organization from legacy data systems — such as on-premise warehouses, outdated ETL tools, and spreadsheet-based reporting — to a modern, cloud-based data platform. They typically cover assessment, target architecture design, data and pipeline migration, data warehouse or lakehouse modernization, governance and security, and preparing data for analytics and AI.
Data Modernization at a Glance
Question | Answer |
|---|---|
What it is | Moving from legacy data systems to a modern, cloud-based, AI-ready data platform |
Core deliverables | Current-state assessment, target architecture, modernization roadmap, migrated data and pipelines, governance setup, documentation |
Typical legacy systems | On-premise SQL Server or Oracle warehouses, Teradata, Netezza, Hadoop, SSIS and Informatica jobs, Excel-based reporting |
Typical modern platforms | Snowflake, Databricks, BigQuery, Redshift, Microsoft Fabric, with dbt, Airflow, and modern BI |
Approach | Phased waves that deliver value early, with old and new systems running side by side |
Engagement models | Modernization assessment and roadmap, phased modernization program, ongoing platform support |
Signs You Need Data Modernization
Reports arrive a day or more late. Batch jobs are slow and fragile.
Your ETL tool is a bottleneck. Few people can maintain it, and licensing is expensive.
Your warehouse can't scale. Storage and compute are fixed by hardware.
Spreadsheets fill the gaps. Business teams rebuild reports by hand because the platform can't keep up.
You can't use AI on your data. Data is locked in systems that modern AI tools can't reach.
Security and compliance are hard to prove. Access, lineage, and audit trails are unclear.
What a Modern Data Platform Looks Like
Layer | Legacy approach | Modern approach |
|---|---|---|
Ingestion | Nightly batch exports and custom scripts | Managed connectors, change data capture, and streaming where needed |
Storage | Fixed on-premise warehouse | Cloud warehouse or lakehouse that scales on demand |
Transformation | GUI ETL tools or stored procedures | Version-controlled, tested transformations (for example, dbt) |
Orchestration | Scheduled scripts with no monitoring | Orchestration with retries, alerts, and lineage |
Governance | Ad hoc permissions and tribal knowledge | Central catalog, role-based access, masking, and audit logs |
Consumption | Static reports and spreadsheets | Self-service BI, embedded analytics, and AI applications |
Our Data Modernization Services
Modernization assessment
We map your current systems, data flows, costs, pain points, and dependencies, and score how ready your data is for analytics and AI. This often starts with a data readiness assessment.
Target architecture design
We design the future platform — cloud, warehouse or lakehouse, ingestion, transformation, orchestration, governance, and BI — and explain every choice in plain language.
Modernization roadmap
We build a phased roadmap with migration waves, milestones, costs, and quick wins, so value arrives early rather than at the end.
Data warehouse modernization
We move legacy warehouses to modern platforms such as Snowflake, BigQuery, or Databricks, converting schemas, SQL, and stored procedures. See data warehouse consulting.
Pipeline modernization
We replace legacy ETL jobs with modern, monitored pipelines and tested transformations using tools such as dbt and Airflow.
Database modernization
We upgrade or migrate operational databases to modern engines and managed cloud services.
Governance and security
We set up a data catalog, role-based access, masking, lineage, and audit logging as part of the new platform, not as an afterthought.
AI readiness
We structure, document, and govern data so the new platform can power RAG assistants, AI agents, and machine learning from day one, through our AI data services.
Decommissioning
We help retire legacy systems safely once the new platform is proven, so you stop paying for both.
How It Works
Step 1: Discover
We assess systems, data, pipelines, reports, costs, and goals.
Step 2: Design
We design the target architecture and agree it with your team.
Step 3: Plan
We build the roadmap and migration waves, with quick wins first.
Step 4: Build the foundation
We set up the cloud platform, security, and core pipelines.
Step 5: Migrate in waves
We move data, pipelines, and reports wave by wave, validating each before switching users.
Step 6: Optimize and retire
We tune performance and cost, then decommission the legacy systems.
What You Get
A clear assessment of your current data estate
A target architecture and phased roadmap
A modern, cloud-based data platform
Migrated, validated data, pipelines, and reports
Governance and security built in
An AI-ready foundation and decommissioned legacy systems
Who This Is For
Mid-size companies on legacy warehouses | Teams stuck on old ETL tools | Organizations planning AI | Companies after mergers |
|---|---|---|---|
Need a scalable cloud platform without a disruptive big-bang project | Need maintainable, monitored, version-controlled pipelines | Need data structured and governed for AI use cases | Need several data estates consolidated onto one modern platform |
Why Work With Codersarts
Modernization programs fail when they try to change everything at once, or when the new platform simply copies old problems. We modernize in waves that each deliver value, validate every migrated dataset, and design for AI from the start. Our team spans data engineering, cloud platforms, BI, and AI, so every layer of the new stack works together.
Frequently Asked Questions
What is data modernization?
Data modernization is the process of moving from legacy data systems to a modern, cloud-based data platform with automated pipelines, scalable storage, strong governance, and support for analytics and AI.
Why is data modernization important for AI?
AI systems need data that is clean, connected, current, documented, and governed. Legacy platforms often lock data in silos and batch jobs, so modernization is usually the first step before AI can deliver value.
How long does data modernization take?
An assessment and roadmap take a few weeks. The modernization itself is delivered in phases, typically over several months for mid-size organizations, with useful results from the first wave.
How much do data modernization services cost?
The assessment and roadmap are a fixed-scope engagement. Program cost depends on the number of systems, data volume, pipelines, and reports, and is estimated wave by wave in the roadmap.
Do we have to move everything at once?
No. A phased approach is safer and delivers value sooner. Old and new systems run side by side until each wave is validated.
What's the difference between data modernization and data migration?
Data migration moves data from one system to another. Data modernization is broader: it redesigns the whole data platform — ingestion, storage, transformation, governance, and consumption — and usually includes several migrations along the way.
Which modern data platform should we choose?
It depends on your cloud, team skills, workloads, and budget. Snowflake, Databricks, BigQuery, and Microsoft Fabric are the most common choices, and we recommend based on your requirements.
Can you modernize our reports too?
Yes. We rebuild legacy and spreadsheet reports on modern BI tools such as Power BI and Tableau, connected to the new platform. See business intelligence.
