DATABASE MODERNIZATION

DATABASE MODERNIZATION

Move the database. Modernize the estate around it.

Datachecks helps retire legacy database platforms by migrating the data, procedural logic, jobs, integrations and dependent workloads required to run them on modern target platforms.

WHEN THIS SERVICE FITS

When the database has become the constraint.

01

Legacy platform cost

The database is expensive to operate, scale or maintain.

02

Modernization pressure

The organization wants to move workloads to a modern cloud data platform.

03

Procedural complexity

Years of SQL, stored procedures, jobs and business logic make migration difficult.

04

Platform retirement

The goal is to safely decommission the legacy database and dependent workloads.

WHAT ACTUALLY GETS MODERNIZED

A database migration is bigger than schemas and tables.

Cutover and retirement

A database migration is complete only when the target can safely replace the legacy database and the workloads around it.

PRIMARY DATABASE MODERNIZATION SCENARIOS

Common database modernization paths.

Oracle → Snowflake

Modernize Oracle data, PL/SQL, procedures, jobs, ETL and downstream dependencies into Snowflake.

Explore Oracle → Snowflake

Oracle → Databricks

Move Oracle data and dependent workloads into a Databricks-native architecture.

Explore Oracle → Databricks

SQL Server → Snowflake

Modernize SQL Server databases, T-SQL, SSIS and scheduled jobs into Snowflake.

Explore SQL Server → Snowflake

SQL Server → Databricks

Move SQL Server data, T-SQL workloads and dependent pipelines into Databricks.

Explore SQL Server → Databricks

Also supporting DB2 and other database modernization scenarios based on source and target architecture

LEGACY DATABASE → TARGET PATTERN

Modernize the implementation—not just the syntax.

LEGACY DATABASE

MODERN TARGET

Tables / Views

Target tables / views

PL/SQL / T-SQL

Target-native SQL / Python / Spark

Stored Procedures

SQL / target-native services / redesigned implementation

Scheduled Jobs

Target-native or external orchestration

CDC

Modern ingestion / streaming pattern

ETL

Native pipelines / dbt / modern ELT

Security

Target governance / RBAC

Dependencies

Modern downstream architecture

CONVERT

MODERNIZE

RETIRE

Not every source component should be translated one-to-one. Datachecks determines what should be converted, redesigned or retired.

THE DIFFICULT PARTS

The hard work usually lives in the logic around the database.

Complex PL/SQL / T-SQL

Stored procedures and packages

Stateful processing

Temporary table patterns

Source-specific functions

Scheduler dependencies

CDC semantics

ETL coupling

Security translation

Hidden business rules

Downstream application dependencies

Business reconciliation

Repeatable patterns are automated. Complex patterns become explicit exceptions with owners and evidence.

Migration Experts

Architecture, exceptions and every sign-off.

Migration Evidence

Object-level proof connected across the lifecycle.

Automation at scale. Human judgment where it matters.

NATIVE TOOLS + DATACHECKS

Use platform-native migration capabilities where they are strongest.

Datachecks works with destination-native migration tools and adds whole-estate discovery, semantic mapping, exception handling, business validation and migration evidence around them.

PART OF DATA ESTATE MIGRATION

Database Modernization is one type of Data Estate Migration.

When the database is the center of gravity, this service focuses the broader Datachecks migration model on database objects, procedural logic, jobs, integrations and dependent workloads.

FAQ

Frequently asked questions

What happens to PL/SQL, T-SQL and stored procedures?

Are scheduled jobs and CDC in scope?

How is database security and role translation handled?

What about downstream applications that depend on the database?

Is this the same as Data Platform Modernization?

How is equivalence proven before the legacy database is retired?

Planning to retire a legacy database?

Start with the database estate, dependent workloads and target architecture. Datachecks can assess the complexity and take the migration through production readiness.
