All versions of UA are officially deprecated and have been replaced by DMA for your migration needs. The core differences between the tools are as follows:

  • UA only provides assessments migrating to on-premises SQL targets, but DMA extends to Azure Database platforms as well.
  • You need to have a specific UA tool, per each target SQL Server version, but DMA is a unique tool and supports all target SQL versions, starting SQL Server 2012.
  • UA enables assess the workload traces, but DMA only assess the schema and static objects.
  • All versions of UA is officially deprecated and replaced by DMA.
