How Do I Optimize a Windows Target Server After the Migration Is Complete?

Scenarios

After the migration is complete, you need to manually install drivers on the target server to solve compatibility issues.

Procedure

1. Sign in to the console.
2. Under Compute, click Elastic Cloud Server.
3. In the ECS list, view the flavor of the target ECS.

   ECS flavors are named in the "AB.C.D" format, for example, m2.8xlarge.8.

   A specifies the ECS type. B specifies the type ID. C specifies the flavor size. D specifies the ratio of memory to vCPUs expressed in a digit. For details about ECS flavors, see ECS Types.

   • If B of the target ECS is 1, for example, s1.small.2, the ECS uses Xen virtualization, and you will need to install PV drivers.
   • If B of your target ECS is not 1, for example, s2.small.3, the ECS uses KVM virtualization, and you will need to install VirtIO drivers.
4. Check whether the PV drivers or VirtIO drivers software package exists on the target ECS based on the virtualization type queried in 3.
   • If it does, go to 7.
   • If it does not, go to 5.
5. Download the PV drivers or VirtIO drivers package to the source server based on the virtualization type queried in 3. For more information, see Obtaining Required Software Packages.
6. Synchronize the PV driver or VirtIO drivers software package from the source server to the target ECS, and then go to 7.
7. Install the required drivers on the target ECS.
   1. If the target ECS uses KVM virtualization, you need to install the VirtIO drivers, for details, see Installing VirtIO Drivers.
   2. Installing PV Drivers
