You might have more folders on your volumes that you currently share out locally as SMB shares to your users and apps.

A single Windows Server instance (or cluster) can sync up to 30 Azure file shares. In this step, you'll determine how many Azure file shares you need.

Phase 1: Identify how many Azure file shares you need If you are returning to this article, use the navigation on the right side to jump to the migration phase where you left off. The following sections describe the phases of the migration process in detail. Once it's time for the actual data copy, you'll need to consider repeated, differential RoboCopy runs to minimize downtime, and finally, cut-over your users to the newly created Azure file shares.

Furthermore, you'll configure networking, consider a DFS Namespace deployment (DFS-N) or update your existing one. You'll need to deploy Azure storage accounts and file shares. The migration process consists of several phases. The latter requires keeping downtime to a minimum, so that it can fit into or only slightly exceed regular maintenance windows. This migration needs to be done in a way that guarantees the integrity of the production data and availability during the migration. In Azure, you'll store you data in native Azure file shares you can use without a need for a Windows Server. The goal is to move the data from existing file share locations to Azure. At this time AzCopy is not a recommended tool for migration scenarios with Azure file shares as the target. That makes for an incomplete differential-copy feature set. An important difference to AzCopy -sync is that deleted files on the source will not be removed on the target. However, there are still gaps and there can easily be misunderstandings of functionality when comparing AzCopy flags to RoboCopy flags.Īn example: RoboCopy /MIR will mirror source to target - that means added, changed, and deleted files are considered. Check out the file fidelity section in the migration overview article to learn more about the importance of copying files at maximum possible fidelity.ĪzCopy, on the other hand, has only recently expanded to support file copy with some fidelity and added the first features needed to be considered as a migration tool.

RoboCopy supports many migration scenarios due to its rich set of features and the ability to copy files and folders in full fidelity.

RoboCopy, as a trusted, Windows-based copy tool, has the home-turf advantage when it comes to copying files at full fidelity. AzCopy is a "born-in-the-cloud" tool that can be used to move data as long as the target is in Azure storage.

RoboCopy uses any version of the SMB protocol. Premium file shares (FileStorage), LRS/ZRSĪzCopy and RoboCopy are two fundamentally different file copy tools. Look through the table of migration guides to find the migration that best suits your needs. There are many different migration routes for different source and deployment combinations.
