Ability to perform learning data loads using Data Load Wizard will be deprecated with and end-of-life in the Feb 2021 Release. DLW is a legacy data load tool which was built on older technology, is accessed using an older user interface (UI), and experiences slow performance and limited load type support.
Edge Import addresses these issues with a modern UI and an intuitive workflow that can support a greater number of concurrent loads, while providing administrators with a delightful user experience.
Existing organizations that are ready to migrate to Edge Import can enable it in the Edge Marketplace and review the migration and starter guides to help them through the migration steps. All organizations are required to complete their migrations before the February '21 Release which will be the end-of-life date for DLW learning data loads.
