 :exclamation: The module does not support major version upgrades or updates to encryption and backup encryption keys. To upgrade the version, create another instance of Databases for EnterpriseDBs with the updated version.
 
 ## Usage
-
 IBM Cloud Databases supports only Key Protect encryption for backups, not Hyper Protect Crypto Services. If you enable key management encryption and no value is passed for 'backup_encryption_key_crn', the value of 'kms_key_crn' is used. And if a HPCS value is set for `kms_key_crn`, the database backup encryption uses the default encryption keys. For more information, see [Hyper Protect Crypto Services Integration](https://cloud.ibm.com/docs/cloud-databases?topic=cloud-databases-hpcs) in the IBM Cloud Docs.
