Log on to the primary replica server, right-click the virtual machine that has replication technology enabled, expand Network adapters, tap TCP/IP in failover, at which point administrators can use these network settings to control the static IP address that is used when the virtual machine is started as part of a failover. If you configure this virtual machine to use dynamically assigned IP addresses, you do not need to configure these settings. Regardless of the type of failover that an administrator uses, you first need to make sure that these values are set on both the current primary and replica servers. The affected virtual machine and the server on which it is running must use the same version of Hyper-V Integration Services (that is, the Hyper-V integration service may need to be updated)

Log on to the secondary replica server, right-click the virtual machine that has replication technology enabled, expand Network adapters, and tap test failover. Specifies the configuration of the network adapter used by the test replica virtual machine. When you select a test failover task on a replica virtual machine, a test replica virtual machine is created.

Test failover

1. Log on to the primary replica server and right-click the virtual machine with replication technology enabled

2. Select Copy and click "Test Failover"

Performing a fail-over

1. Open Hyper-V Manager, right-click on the replica's virtual machine, select "Enable Replication"

2. Specify the replica server page, specify the replica server, click Next

6. Configure additional recovery point pages, which the administrator can configure to store only recently received replication data, and update the data on the replica server based on the frequency of replication that you configure. You can also configure replicas to retain an additional one or more recovery points, which are created approximately once per hour. Having additional recovery points also allows you to restore virtual machine operations to an earlier point in time when performing a failover. You can keep up to 15 (24 in Windows Server R2) Such a recovery point to record the number of recovery points that you need.

7. Select the initial replication Method page, in order to begin copying data, the replica needs to transfer the current state of the virtual machine. This initial state can be transmitted directly through the existing network, immediately or later, when you configure it. You can also use a pre-existing restored virtual machine on the replica server (for example, if you have restored an earlier backup of the virtual machine on the replica server) as the initial copy. Alternatively, you can save network bandwidth by replicating the initial copy to external media and then physically passing media to the replica site. Record the initial replication method that you plan to use.
