Migrating On Prem File Shares to Azure Files

Wagner, Richard (Cognizant) 66 Reputation points

Hello, I am migrating about 20 files shares (100gb total size) from on prem to Azure Files. The goal of coarse is to migrate as seamless as possible so users don't realize changes occurred so I need to keep all meta data, ACLs, permissions, etc. The end users connect to these shares via gpo so they won't really notice if the share path looks different. There is one on prem file server at a total of 2 sites running on vmware. I have built an azure environment made up of a domain controller (azure vms)
that i will migrate later and a vm for AD connect (syncing on prem to azure).

I'm using a LRS, gen purpose standard V2 storage account. I'm wondering if I should just create the same number of file shares in azure files that I have on prem and just robo copy the data from each share on prem to each new share or should i use azure file sync? The overall goal is the have all data synced, test share permissions, cut over new shares and eol old file servers. I already have the storage account added to active directory and synced on prem AD resources to AD connect. Let me know what you think is best and easiest.

If you have any other tips or things to watch out for please let me know. Thanks so much!

    Linking to the Migrate to Azure file shares documentation as it provides some good recommendations depending on your exact scenario. Since you are not intending to keep your on-premise servers for caching, I would probably learn towards robocoby as this will be the easiest setup. Depending on your performance needs you might consider putting the file shares in different storage accounts. If they are all in a single storage account this could affect the performance. For more information see Azure Files scalability and performance targets.

    Hope this helps. Let us know if you have further questions or issues and we will be happy to help.
