We had a bunch of legacy warehouses, which we wanted to consolidate, as well as stay up-to-date with warehousing options. This is why we moved into Teradata.

Since we also use the AWS PostgreSQL, and some of our data is in there too, we came to the conclusion to move solutions within Teradata. Because already had the on-premise Teradata, it was easy for us to migrate from on-premise Teradata to AWS Teradata.
