Data modernization that brings every system onto one data foundation
Bring CRM, billing, and network systems onto one trusted source. Match duplicate records and reconcile mismatched formats along the way.
Whether your platform is based on legacy systems, frankensteined together from acquisitions that brought their own CRM, billing platform, and data warehouses, or designed by previous leaders and not working for your current business, DAS42 migrates all of it onto Snowflake.
We help you build the logic to match records across sources, and validate before you cut over to production.
How DAS42 handles data modernization
Discovery & assessment
Audit every source system, map compliance requirements, and set the target architecture before any code gets written.
Migration build
Map, transform, and validate data in version-controlled Snowflake DCM Projects, built and tested in a sandbox first.
Cutover & handover
Run the new environment in parallel until the numbers are reconciled between old and new systems, then cut over and hand your team the Git repo and the training to run it.
Snowflake migration, from whatever data platform you’re on now
Whether the target is a single Snowflake data warehouse, a Snowflake data lake for semi-structured content, or Iceberg tables for open-format storage, DAS42 handles the migration end to end. Recent migration paths include:
- SQL Server to Snowflake
- Teradata to Snowflake
- SAS to Snowflake
- Hadoop to Snowflake
- BigQuery to Snowflake
- Databricks to Snowflake
What you get
Reference Architecture
A target reference architecture document defining the destination schema and migration priorities
Migration & Transformation
Migration and transformation logic built in Snowflake DCM Projects, version-controlled and auditable
Sandbox Testing
A sandbox environment where every pipeline is tested before it touches productions
Migration Validation
A validation report comparing old and new environments query for query before cutover
Cutover Planning
A cutover plan timed to your business calendar, not a vendor’s default schedule
Training & Handoff
Documentation and hands-on training so your team runs the new environment without DAS42
Proof & Perspective
DAS42 helped Zayo Group migrate off a patchwork of billing, CRM, and network systems built up over years of acquisitions. The team consolidated root-cause events buried across thousands of daily network alerts and cut incidents by 15% company-wide.
Thanks to Snowflake and DAS42 we can ingest and integrate data much more rapidly than we’ve done in our past, and we keep the solutions really simple. That makes us more efficient in the long run and much more cost effective as well.
