 - Only [software and HSM RSA keys](../articles/key-vault/keys/about-keys.md) of sizes 2,048-bit, 3,072-bit and 4,096-bit are supported, no other keys or sizes.
     - [HSM](../articles/key-vault/keys/hsm-protected-keys.md) keys require the **premium** tier of Azure Key vaults.
 - For Ultra Disks and Premium SSD v2 only: Snapshots created from disks that are encrypted with server-side encryption and customer-managed keys must be encrypted with the same customer-managed keys.
+- Disks using incremental snapshots and incremental snapshots themselves can't be copied to different encryption sets.
 - Most resources related to your customer-managed keys (disk encryption sets, VMs, disks, and snapshots) must be in the same subscription and region.
     - Azure Key Vaults may be used from a different subscription but must be in the same region as your disk encryption set. As a preview, you can use Azure Key Vaults from [different Azure Active Directory tenants](../articles/virtual-machines/disks-cross-tenant-customer-managed-keys.md).
 - Disks encrypted with customer-managed keys can only move to another resource group if the VM they are attached to is deallocated.
