Migrating from Fivetran to dlt involves standardizing data pipelines for organizations prioritizing control, customization, and cost efficiency. While Fivetran offers ease of use and pre-built functionality, dlt provides a code-first customizable solution with robust metadata fields for effective tracking and auditing. By consolidating historical and new data into unified views, teams can ensure a seamless transition without sacrificing data integrity or performance. A similar approach can be applied to other data sources like Salesforce, Shopify, and SQL databases.
