 ### Provisioned v2 migrations
-Migrating your SMB Azure file shares from a pay-as-you-go model to the provisioned v2 billing model involves the same process as migrating file shares from any other SMB source. See [Migrate to SMB Azure file shares](storage-files-migration-overview.md). We recommend using [Robocopy](storage-files-migration-robocopy.md) or [Azure Storage Mover](migrate-files-storage-mover.md).
+The process for migrating your SMB Azure file shares from a pay-as-you-go model to the provisioned v2 billing model differs depending on whether or not you're using Azure File Sync. 
+
+- If you're using Azure Files without Azure File Sync, see [Migrate files from one SMB Azure file share to another](migrate-files-between-shares.md).
+- If you're using Azure File Sync, see [Migrate files from one Azure file share to another when using Azure File Sync](../file-sync/file-sync-share-to-share-migration.md).
 
 ## Provisioned v1 model
 The provisioned v1 method provides storage, IOPS, and throughput in a fixed ratio to each other, similar to how storage is purchased in an on-premises storage solution. When you create a new provisioned v1 file share, you specify how much storage your share needs, and IOPS and throughput are computed values. The provisioned v1 model for Azure Files is only available for SSD file shares.
