Cloud Data Platform Migration

Plan and migrate data workloads to Snowflake.

On this page

Move workloads with a clear cutover plan

A migration should address a specific limitation in your current platform. We assess workloads, dependencies and operating costs before planning a move to Snowflake.

The work covers source mapping, SQL conversion, reconciliation and cutover. If the main problem is inconsistent models, reporting or maintenance within an existing warehouse, start with Data Warehouse Modernization.

Key Benefits

Continuity through the move

Plan migration stages around reporting deadlines, dependencies and an agreed rollback path.

Savings of Up to 70%

We've seen Snowflake cost reductions of up to 70% through optimization. Your opportunity depends on the starting workloads and configuration; for a migration, we evaluate the full operating cost before recommending a move.

Access checked before cutover

Map existing permissions to Snowflake roles and policies, then test who can access each dataset.

A target your team can operate

Leave tested deployment routines, monitoring and runbooks with the people responsible for the new platform.

Our Snowflake Migration Services

1

Snowflake Migration Strategy

Map source data, transformation logic and report dependencies. Assess compatibility and the business case before choosing which workloads to move.

2

Target account setup

Snowflake manages the underlying infrastructure on AWS, Azure, or GCP. We configure the account, access controls and warehouses so your team can focus on data instead of maintaining servers.

3

Data and SQL conversion

Move data and adapt SQL, stored procedures and load schedules for Snowflake. Update the dependencies and connections needed in the new environment.

4

Reconciliation and workload testing

Compare data and report results with the source, investigate differences and test query performance, access and cost before the business switches over.

5

Cutover and handover

Repoint reports and downstream consumers, monitor the transition and agree when old jobs can be retired. Document recovery steps and ongoing ownership.

What changes when you move to Snowflake

Moving from AWS/Azure/GCP Data Services

  • • Infrastructure Retirement: Identify which servers or clusters the migrated workloads no longer need
  • • Workload Performance: Validate SQL performance and warehouse sizing against your workloads
  • • Service Consolidation: Decide which processing services Snowflake can replace and which integrations remain
  • • Flexible Compute: Size warehouses for each workload, with auto-suspend and scaling controls to manage spend

Moving from On-Premises Systems

  • • Hardware Retirement: Decommission the systems no longer needed after cutover and validation
  • • SQL and Pipeline Changes: Adapt the logic that needs to change for the target platform
  • • Elastic Capacity: Expand capacity without buying hardware, while planning for concurrency and cost
  • • Recovery Planning: Configure replication and test recovery against your recovery requirements

Decisions before cutover

  • • Result Reconciliation: Agree which reports and business measures must match, and who signs them off
  • • Recovery: Test the rollback path and retention settings before switching consumers
  • • Consumer Access: Validate BI connections, roles and any shared datasets with their owners
  • • Retirement: Agree when old pipelines, servers and contracts can be retired, including any overlap costs

Our Snowflake Migration Process

1

Assess

Inventory workloads, dependencies and the operating-cost baseline.

2

Design

Map source structures, access rules and SQL compatibility.

3

Migrate

Move data in stages with reconciliation and a rollback plan.
