@Freaks on Me ,
Thank you for reaching out to the Microsoft Q&A platform. Happy to answer your question.
You can't convert an existing standard performance storage account to a block blob storage account with premium performance. To migrate to a premium performance storage account, you must create a premium block blob account, and migrate the data to the new account. For more information, see Create a BlockBlobStorage account.
To copy blobs between storage accounts, you can use the latest version of the AzCopy command-line tool. Other tools such as Azure Data Factory are also available for data movement and transformation.
- Once you've created a file share in a storage account, you cannot move it to tiers exclusive to different storage account kinds. For example, to move a transaction-optimized 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, but you may also use tools like robocopy on Windows or rsync for macOS and Linux.
- Azure Files supports two storage tiers: premium and standard. Standard file shares are created in general purpose (GPv1 or GPv2) storage accounts and premium file shares are created in FileStorage storage accounts.

- Microsoft provides services and utilities for importing your data from on-premises storage devices or third-party cloud storage providers. Which solution you use depends on the quantity of data you're transferring.
