The migration tool requires the backed-up data to be available on the appliance. For copying the backup from Windows server to Appliance, you need the network connectivity. For restore to work, the migration tool expects the appliance to have the same network identity as Windows. As you cannot have multiple devices in the network with the same network identity, there are two options for copying the backup to appliance:
Copying the backed-up data using temporary location
Copying the backed-up data directly to ZENworks Appliance
The backup_zips folders created as part of the backup process can be copied either to a temporary location, network share, or USB disc. In this approach, the data needs to be transferred from Windows Server to a temporary location and it should be copied back to the appliance. This might be time consuming depending on the size of backed-up data.
NOTE:If you do not have prior Linux experience, then ZENworks recommends this approach.
To copy the backed-up data from a temporary location, perform the following steps:
Copy the backed-up data created on the Windows server to the temporary location.
Power off the Windows server or disconnect the network adaptor.
NOTE:Do not power on the Windows server. If the Windows server is powered on, any changes made (performed by an administrator, or any processing done by any of the processes) will not be in the backup. And these changes may be lost after restoring. Also, this might lead to zone in-stability. In case Windows server needs to be powered on, ensure it is not connected to the network and does not connect to the database.
Deploy ZENworks 23.4 Appliance and configure it with the same IP address, DNS name, and time zone as that of the Windows Primary Server. Ensure the vastorage disk has sufficient disk space (more than double the size of backup_zips folder). For more information, see Appliance Deployment.
Create a directory, say migration, on Appliance /vastorage disk and copy the backed-up data from the temporary location to this directory.
You will be deploying the appliance with a temporary IP address and DNS name. Using third-party tools, you can copy the backed-up data from the Windows Primary Server to Appliance directly. Once the data is copied to the appliance, you need to shut down the Windows Primary Server and re-configure the IP an DNS name of the appliance to match the Windows Primary Server. This approach will be faster than the previous approach. But, you might need some experience with Linux.
To copy the backed-up data directly to the target appliance, perform the following steps:
Deploy ZENworks 23.4 Appliance and configure it with same time zone as that of Windows Primary Server and a temporary IP address, DNS name. Ensure the vastorage disk has sufficient disk space (more than twice the size of backup_zips folder). For more information on configuring appliance, see Appliance Deployment.
Start the SSH service on the appliance using the following command:
systemctl start sshd.service
Update firewall configuration to allow SSH service.
Create a directory, for example- migration, on Appliance /vastorage disk.
Copy the backed_zips from Windows Primary Server to the directory created in the previous step, using any third-party utility. This needs to be done from the Windows Primary Server.
Power off the Windows server or disconnect the network adaptor.
NOTE:Do not power on the Windows server. If the Windows server is powered on, any changes made (performed by an administrator, or any processing done by any of the processes) will not be in the backup. And these changes may be lost after restoring. Also, this might lead to zone in-stability. In case Windows server needs to be powered on, ensure it is not connected to the network and does not connect to the database.
Reconfigure the IP and DNS of the appliance to match that of the Windows primary server. This can be done using YaST2. For more information, see Reconfiguring Network Adapters on ZENworks Appliance.
