   Table 1 Parameters required for creating a server template

   Parameter	Description
   Template Name	User-defined
   Region/Project	Select a region and project where you want to provision and manage target servers. By default, the region is the one set in the default migration template, but you can change it as needed.
   AZ	The parameter is set to Random by default. You can also select another AZ.
   Disk	Select a disk type as required. Available disk types depend on the AZ.
   VPC	If you select Create new, SMS will recommend a VPC when you use this template to configure a target server. You can also create or select a VPC based on the same rules. If the source server's IP address is 192.168.X.X, you are advised to create a VPC and a subnet that both belong to network range 192.168.0.0/16. If the source server's IP address is 172.16.X.X, you are advised to create a VPC and a subnet that both belong to network range 172.16.0.0/12. If the source server's IP address is 10.X.X.X, you are advised to create a VPC and a subnet that both belong to network range 10.0.0.0/8.
   Subnet	If you select Create new, SMS will recommend a subnet when you use this template to configure a target server. The subnet must be in the same network range as the VPC.
   Security Group	If you select Create new, SMS will recommend a security group when you use this template to configure a target server. You can also create or select a security group that opens the following inbound ports: Windows: ports 8899, 8900, and 22 Linux: port 22 for file-level migration, and ports 8900 and 22 for block-level migration CAUTION: For security purposes, you are advised to only allow traffic from the source server to the ECS over these ports. The firewall of the target server must allow traffic to these ports.
