Data Management

​Migrating a legacy data warehouse from Teradata to Microsoft Azure Synapse 

​Migrating a legacy data warehouse from Teradata to Microsoft Azure Synapse involves several steps : 

IMAGE FOR STEPS TO MIGRATE  A legacy data warehouse from Teradata to Microsoft Azure Synapse

1. Data Assessment: Assess the current state of your legacy data warehouse, including the amount of data, the complexity of the schema, and the dependencies on existing systems. This will help you determine the scope and complexity of the migration project. 

​2. Data Cleanup: Clean up your data to ensure that it’s in a suitable format for migration. This may involve removing duplicates, fixing inconsistencies, and transforming data into a format that is compatible with Azure Synapse.

​3. Data Export: Export the data from your legacy data warehouse in a format that can be easily imported into Azure Synapse. This may involve using tools such as Teradata’s SQL Assistant or Teradata Parallel Transporter. 

​4. Data Import: Import the data into Azure Synapse using Azure Data Factory or Azure Synapse Studio. This may involve mapping the data from the Teradata format to the Azure Synapse format and creating the necessary data structures in Azure Synapse. 

  1. ​Data Validation: Validate the data in Azure Synapse to ensure that it has been successfully imported and that the data is consistent and accurate. 
  1. ​Data Transformation: Transform the data in Azure Synapse as needed to support your business requirements. This may involve creating new columns, aggregating data, or transforming data into a different format. 
  1. ​Data Loading: Load the transformed data into Azure Synapse and begin using it for your business intelligence and analytics needs. 

​It’s important to have a detailed plan in place and to allocate enough resources to complete the migration project. You may also need to engage with Microsoft or a partner to provide additional support and guidance.
