@Alibrahim, Mohamad Welcome to Microsoft Q&A Forum, Thank you for posting your query here!
Upgrading a v1 storage account to a general-purpose v2 account is free. You may specify the desired account tier during the upgrade process. If an account tier is not specified on upgrade, the default account tier of the upgraded account will be Hot. However, changing the storage access tier after the upgrade may result in changes to your bill so it is recommended to specify the new account tier during upgrade.
For more information on the pricing model for storage accounts, see Azure Storage Pricing page. For more information on outbound data transfer charges, see Data Transfers Pricing Details page.

Upgrading a general-purpose v1 or Blob storage account to general-purpose v2 is permanent and cannot be undone.
Upgrading to a general-purpose v2 storage account from your general-purpose v1 or Blob storage accounts is straightforward. You can upgrade using the Azure portal, PowerShell, or Azure CLI. There is no downtime or risk of data loss associated with upgrading to a general-purpose v2 storage account. The account upgrade happens via a simple Azure Resource Manager operation that changes the account type.
You are not billed for transactions related to the automatic generation of snapshots or versions when a blob is overwritten or deleted. You are billed for calls to the Undelete Blob operation at the transaction rate for write operations.
There is no charge to enable point-in-time restore. However, enabling point-in-time restore also enables blob versioning, soft delete, and change feed, each of which may result in additional charges. Billing for point-in-time restore depends on the amount of data processed to perform the restore operation. The amount of data processed is based on the number of changes that occurred between the restore point and the present moment. For more information, click here
- Enabling blob versioning can result in additional data storage charges to your account. When designing your application, it is important to be aware of how these charges might accrue so that you can minimize costs. For more information, see here
- The costs for Blob Storage Soft Delete are explained here: Soft delete for Blob storage - Pricing and billing
All soft deleted data is billed at the same rate as active data.
Soft delete and versioning charges the capacity being used by soft deleted blobs, or versions.
The exact cost depends on how often your data is modified or deleted. If you didn’t modify anything or delete anything. There is no extra cost. If all 100GB is deleted, then you are paying for the 100GB for 30 days of the soft delete.
You can use the Azure Storage pricing calculator to help estimate your costs.
