You can restore an Amazon RDS instance to the same AWS cloud account or to a different AWS cloud account. You can restore to a selected target availability zone and change the node type of the instance during the restore.
Note: Restoring an Amazon RDS instance to a different cloud account is supported using STS Assume role based authentication or access keys for the target account.

The Restore options dialog box appears.
To restore the instance to a different cloud account, from the Cloud account list, select the cloud account.
The cloud account that is displayed when the dialog box first appears is the account that owns the backup.
In the Database identifier box, enter a name for the instance that will be created from the snapshot.

To define which subnets and IP ranges the cluster or instance can use in the Amazon virtual private cloud (VPC), in the VPC security group IDs box, enter the names of the security group ID.
You can add multiple security groups, separated by commas. For example, you can enter "sg-1122,sg-3344".
For a cross-region replication and restore, if you don't want to use the default value, you must enter the security group ID.
