+          For DMS(Classic)-
           * Use the multi CPU General Purpose Pricing Tier when you create your service instance to allow the service to take advantage of multiple vCPUs for parallelization and faster data transfer.
           * Temporarily scale up your Azure SQL Database target instance to the Premium tier SKU during the data migration operation to minimize Azure SQL Database throttling that may affect data transfer activities when using lower-level SKUs.

+          For DMS-
+          * DMS uses SHIR node as its compute, if you are copying backups from local file share to Azure blob storage OR while performing migration to Target Azure SQL DB. So ensure to monitor the resrouce usage of SHIR node.
+          * Temporarily scale up your Azure SQL Database target instance to the Premium tier SKU during the data migration operation to minimize Azure SQL Database disk throttling that may affect data transfer activities when using lower-level SKUs.
