4 Methods of Migrating Proxmox to New Server

Proxmox is a powerful open-source virtualization platform that allows users to manage and deploy virtual machines and containers. By migrating Proxmox to a new server, you can leverage more powerful hardware, expand computing resources, distribute workloads for optimal performance, ensure quick service recovery in case of server failure, and facilitate easier system upgrades and maintenance without interrupting running services.

Why need to migrate Proxmox to new server?

Migrating Proxmox to a new server may be necessary for several reasons, including:

Hardware Upgrade or Replacement: If your current server hardware is outdated, experiencing issues, or you’re upgrading to more powerful hardware, migrating Proxmox to a new server allows you to take advantage of improved performance, reliability, and features.

Capacity Expansion: If your current server is running out of resources such as CPU, RAM, or storage, moving to a new server with higher capacity allows for better scalability and resource management.

Disaster Recovery: In the event of a hardware failure or other catastrophic events, having a backup server allows for quick recovery and minimizes downtime. Migrating Proxmox to a new server can be part of a disaster recovery strategy.

Consolidation or Optimization: If you have multiple servers running Proxmox, you may want to consolidate them onto a single, more powerful server to optimize resource utilization, simplify management, and reduce operational costs.

Method 1: Backup and restore from Proxmox Web interface

1. Back up the virtual machines:

Create a backup of each virtual machine you want to migrate on the original Proxmox server. You can do this through Proxmox’s web interface or the command line.

2. Migrate backup files:

Connect to your old Proxmox server. Use the scp command to copy the backup files from the old server to the new server. For example, if your backup files are in /var/lib/vz/dump/, you can copy them to the same path on the new server using the following command:

scp /var/lib/vz/dump/* root@new-server:/var/lib/vz/dump/

where new-server is the IP address or hostname of your new Proxmox server.

3. Restore the backup:

On the new Proxmox server, you can use the “qmrestore” command to restore those backups, for example:

qmrestore /var/lib/vz/dump/vzdump-qemu-101.vma 101

Method 2: Use Proxmox cluster for migration

1. Create a Proxmox cluster

Log in to the web interface of your old Proxmox server to create a Proxmox cluster.

Select your old server node, click the “Cluster” tab > “Create Cluster" and follow the prompts to enter the cluster's name and other information.

2. Add new servers to the cluster

Log in to the web interface of your new Proxmox server.

Select your new server node, click the “Cluster” tab > Click the “Join Cluster” button and follow the prompts to enter the old server's IP address and root password.

3. Online migration of virtual machines

Log in to the web interface of your old Proxmox server.

Select the virtual machine you want to migrate, click the “Migrate”, In the pop-up migration dialog box, select your new server node and click the “Migrate” button.

Method 3: Migrate using Proxmox Backup Server

1. Install and configure Proxmox Backup Server on your network. You need to set up a repository to store backups of your virtual machines.

2. On your original Proxmox server, configure Proxmox Backup Server as backup storage. You can do this in the Proxmox web interface by clicking "Datacenter > Storage > Add" and select “Proxmox Backup Server”.

3. Create a backup of the virtual machine you want to migrate. You can click “Backup Now” in the “Backup” tab of the virtual machine.

4. On your new Proxmox server, also configure Proxmox Backup Server as backup storage in the same way as step 2.

5. On the new server, you can see the backup you created in step 3. You can click “Restore” and select your backup to create a new virtual machine.
