Innovative Engineering & Construction Company Successfully Migrates from Teradata to Snowflake

The Customer’s Challenge

One of North America's largest engineering and construction firms was looking to move away from its on-premise Teradata data warehouse towards the flexibility and scalability of the Snowflake Data Cloud.

phData’s Solution

Leveraging a combination of modern data stack technologies (HVR for data replication and dbt for script conversion), phData executed a successful migration to Snowflake—all on time and on budget.

The Full Story

The client, a celebrated engineering and construction company, was running into limitations with its existing on-premise Teradata data warehouse. To maximize the power of its data and make it more easily accessible throughout the organization, it looked to the potential of Snowflake. 

Snowflake offered the client several key benefits over Teradata, including:

  • Advanced Performance
  • Broader and More Robust Technology Integrations 
  • Advanced Performance
  • Pay-as-you-go Pricing
  • Better Security

The next step was selecting a partner who knew the ins and outs and all of the technical complexities involved with a smooth transition to Snowflake. 

Having migrated hundreds of clients successfully to Snowflake, the engineering and construction company knew they could count on phData for a seamless move. In a meticulously planned and executed migration strategy, phData orchestrated the shift to Snowflake by leveraging HVR and dbt. 

HVR was implemented for data replication, and dbt was then employed to convert scripts effectively. Despite some initial challenges during the process, the phData team was able to adhere to the designated timeframe and budget.

To solve this problem, the company’s leadership team came together to inspect the current data platform and gaps regarding organizational maturity. Shortly after, they engaged phData to begin work on a data strategy that would evolve their capabilities and make them more agile and insights-driven.
