IP Configuration: Preparing to Migrate

Applies To: Windows Server 2008 R2

This topic helps you prepare to migrate IP configuration settings and data.

Impact on the source server

To prevent IP address conflicts when the source server has static IP addresses that you want to migrate, you must do one of the following after you export configuration from the source server, but before you import IP configuration data from the migration store to the destination server.

  • Disconnect the source server from the network.

  • Change static IP addresses on the source server.

Important

Changing the source server’s IP address can cause roles that are running on the source server to fail.

Impact on the destination server

The destination server has only an intermittent connection to the network from the start of the migration data importation process until importation is complete. During migration, IP configuration settings that are migrated from the source server overwrite IP configuration settings on the destination server.

Important

If you migrate the static IP address from the source server to the destination server, changing the IP address can cause roles that are running on the destination server to fail.

Impact on other servers in your enterprise

Other servers in the enterprise might be affected during IP configuration migration if they depend on server roles or features that are running on the source server.

Impact on other client computers in your enterprise

Client computers cannot access either the source or destination servers during the import process. If the servers from which you are migrating IP configuration data are configured as routers, computers that are configured to use the router will not be able to connect to some networks.

Expected downtime during IP configuration migration

The following conditions can be expected during IP configuration migration.

  • Users cannot access the source server while it is disconnected from the network.

  • After the import operation starts, users cannot access the destination server until the import operation is fully completed.

  • The destination server must be restarted for changes to the IPv6 DisabledComponents property to take effect.

User rights required to perform migration on both source and destination servers

Local Administrator rights are required on both the source and destination servers to perform IP configuration migration.

Preparing the destination server

Prepare the destination server for IP configuration migration by using the following steps.

To prepare the destination server

  1. Install Windows Server Migration Tools on the destination server. For more information, see Windows Server Migration Tools Installation, Access and Removal (http://go.microsoft.com/fwlink/?LinkId=134763).

  2. Verify that all network adapters that you want to configure are enabled and connected to the network.

  3. If you choose to import global IP configuration settings, verify that you can restart the server after the import operation is completed.

Preparing the source server

Perform the following steps to prepare the source server for IP configuration migration.

To prepare the source server

  1. Install Windows Server Migration Tools on the source server. For more information, see Windows Server Migration Tools Installation, Access and Removal (http://go.microsoft.com/fwlink/?LinkId=134763).

  2. Verify that all network adapters that have configurations that you want to migrate are enabled and connected to the network.

Important

Before you run the Import-SmigServerSetting, Export-SmigServerSetting, or Get-SmigServerFeature cmdlets, verify that during migration, both source and destination servers can contact the domain controller that is associated with domain users or groups who are members of local groups on the source server.
Before you run the Send-SmigServerData or Receive-SmigServerData cmdlets, verify that during migration, both source and destination servers can contact the domain controller that is associated with those domain users who have rights to files or shares that are being migrated.

Preparing other computers in the enterprise

Perform the following steps to prepare the source server for IP configuration migration.

To prepare other computers

  • Notify users that they will be unable to access either source or destination servers after the import operation has started, and will not have access until IP configuration migration is complete.
