Thanks to the "Live Migrations" feature available in Hyper-V, it's possible to move virtual machines from one Hyper-V server to another.
To be able to migrate virtual machines from one Hyper-V server to another, it will first be necessary to activate the "Live Migrations" feature on these 2 servers.
In addition, you will need to use one of these 2 authentication methods :
Live migration can work :
For live migration to be possible, your Hyper-V servers will need to :
Note that the compatibility check between the source server and the remote server will be done automatically by the migration wizard.
If your processors are not identical, you will have the option to enable compatibility mode in the settings of the virtual machine that you want to migrate to another Hyper-V server.
But, enabling this setting will also affect the performance of this virtual machine because it will no longer be able to use all the features available in your server's processor.
Indeed, it will be able to use only the basic instructions which are compatible with the processor of the source server and that of the remote server.
To accelerate live migrations, it's better to use a network adapter (and a network) that will be dedicated to that.
As you already know, you can migrate virtual machines dynamically, but live migration is not limited to that.
You can also migrate the storage of a virtual machine (without moving the execution of the virtual machine to another server, for example).
You will also be able to migrate the dynamic memory of a virtual machine (if you use it).
The live migration of a virtual machine, as well as its storage will also cause the migration of its snapshots (checkpoints).
