Migration
To
initiate the magic, right click your VM and select either Migrate Storage or
Migrate Virtual Machine.
Network Migration
When you
are planning to move a VM from a Hyper-V server to another Hyper-V server and
those servers are not in a Hyper-V Cluster, or
you want to move a VM from local storage/LUN over to a CSV on a Hyper-V
Cluster, VMM will perform a Network Migration. You can think of this option as
the same as Export/Import in Hyper-V Manager.
Live Migration
This is
the preferred migration option since it does not include any downtime for your
VMs
when
your VMs are located on a CSV in a Hyper-V Cluster. The details are explained here.
Cluster Migration
This option
is available when a VM runs on a LUN that is not configured as a CSV in a
Hyper-V Cluster. The process will transfer the LUN to another node in that
Cluster. Be careful and make sure that no other VMs runs on the same LUN, since
they will also be transferred. (downtime)
SAN Migration
Same as
above, if you have one VM per LUN, the LUN will be presented for another
Hyper-V server. This migration option is very fast but has some requirements.
The following types of SAN`s support SAN Migration:
·
Fibre
Channel SAN
·
N-Port
ID Virtualization (NPIV) Fibre Channel
·
iSCSI
SAN via Microsoft Initiator
If you
are planning for FC and iSCSI SAN via iSCSI initiator, you will have to use
Microsoft iSCSI Software Initiator – available as a Feature in Windows Server
2008 R2.
NPIV
uses HBA which creates virtual HBA ports with a logical reference to the
underlying physical port.SAN Migration can be used to store VMs from a hypervisor in Library, rapid provisioning, deployment of VMs from Library to a hypervisor, and migrations between servers.
(Both SMI-S and VDS SAN`s support this feature in VMM 2012).
Storage Migration
Move the
physical files for a VM on the same server, from one location to another. You
can do this without – or with minimal downtime. If the VM has multiple VHD`s
associated, then you will be able to specify a new location for every file.
Happy migration and good luck.
