LXD provides tools and functionality to migrate instances in different contexts.
- Migrate existing LXD instances between servers
The most basic kind of migration is if you have a LXD instance on one server and want to move it to a different LXD server. For virtual machines, you can do that as a live migration, which means that you can migrate your VM while it is running and there will be no downtime.
See How to move existing LXD instances between servers for more information.
- Migrate physical or virtual machines to LXD instances
If you have an existing machine, either physical or virtual (VM or container), you can use the
lxd-migratetool to create a LXD instance based on your existing machine. The tool copies the provided partition, disk or image to the LXD storage pool of the provided LXD server, sets up an instance using that storage and allows you to configure additional settings for the new instance.
See How to import physical or virtual machines to LXD instances for more information.
- Migrate instances from LXC to LXD
If you are using LXC and want to migrate all or some of your LXC containers to a LXD installation on the same machine, you can use the
lxc-to-lxdtool. The tool analyzes the LXC configuration and copies the data and configuration of your existing LXC containers into new LXD containers.
