Hello Guys I need to move my AVD user profiles from transaction optimized to premium tier for better performance. I have 105 users with profile storage of 2.5 TB and using Fslogix and currently ongeneral purpose version 2 (GPv2). In my searches i found that i should create a new storage account and move files, check below from MS "to move a transaction optimized (general purpose version 2 (GPv2) storage account) file share to the premium tier, you must create a new file share in a FileStorage storage account and copy the data from your original share to a new file share in the FileStorage account. We recommend using AzCopy to copy data between Azure file shares," although if i go to the "general purpose version 2 (GPv2)" storage account share i can enable "large file shares" i then can enable premium tier, so i am missing something here, do i need to create a new storage account and move files to it or do i can enable through large file shares? also any consideration for both methods? 1- if i move to large file shares do i need downtime and does it affect anything like permissions? 2- if i need to move to a new storage account, what are the steps for the fslogix to keep working and what consideration i should be careful for? thank you in advance

    @Hussein El Moussawi Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

    Large file shares:This field enables the storage account for file shares spanning up to 100 TiB. Enabling this feature will limit your storage account to only locally redundant and zone redundant storage options. Once a GPv2 storage account has been enabled for large file shares, you can't disable the large file share capability. FileStorage storage accounts (storage accounts for premium file shares) don't have this option, as all premium file shares can scale up to 100 TiB.

    The other settings that are available in the advanced tab (hierarchical namespace for Azure Data Lake storage gen 2, default blob tier, NFSv3 for blob storage, etc.) don't apply to Azure Files.

    Enable large file shares on an existing account

    Before you create an Azure file share on an existing storage account, you might want to enable large file shares (up to 100 TiB) on the storage account if you haven't already. Standard storage accounts using either LRS or ZRS can be upgraded to support large file shares without causing downtime for existing file shares on the storage account. If you have a GRS, GZRS, RA-GRS, or RA-GZRS account, you'll either need to convert it to an LRS account before proceeding or register for the Azure Files geo-redundancy for large file shares preview.

    You can't move between standard and premium tiers without physically migrating your data between different storage accounts.
    Understand Azure Files performance

    You can enable premium tier on a general purpose version 2 storage account by enabling large file shares. However, there are some limitations to using large file shares, such as a maximum file size of 100 TiB and a maximum capacity of 100 TiB per share. Additionally, enabling large file shares may require some downtime and could potentially affect permissions. If you want to avoid these limitations and potential issues, you can create a new FileStorage storage account and copy the data from your original share to a new file share in the FileStorage account using AzCopy. This method will require some downtime, but it will allow you to take advantage of the full capabilities of premium tier storage. To move your user profiles to a new storage account, you can follow these general steps:

    1. Create a new FileStorage storage account in the same region as your AVD deployment.
    2. Create a new file share in the new storage account.
    3. Use AzCopy to copy the data from your original share to the new file share in the new storage account.
    4. Update your AVD deployment to use the new file share for user profiles.
    5. Verify that user profiles are working correctly in the new file share.
    6. Delete the old file share and storage account.

    When using FSLogix, you will need to update the configuration to point to the new file share. This can be done by updating the VHDLocations parameter in the FSLogix configuration file to point to the new file share.

    Additional information: If you choose to move to large file shares, you may experience downtime during the migration process. You should also ensure that the permissions are set correctly after the migration
