n
The virtual machines must be properly configured for vMotion. See Virtual Machine Conditions and
Limitations for vMotion
n
Virtual machine disks must be in persistent mode or be raw device mappings (RDMs). See Storage
vMotion Requirements and Limitations.
n
The destination host must have access to the destination storage.
n
When you move a virtual machine with RDMs and do not convert those RDMs to VMDKs, the
destination host must have access to the RDM LUNs.
n
Consider the limits for simultaneous migrations when you perform a vMotion migration without shared
storage. This type of vMotion counts against the limits for both vMotion and Storage vMotion, so it
consumes both a network resource and 16 datastore resources. See Limits on Simultaneous
Migrations.
Migration Between vCenter Server Systems
vSphere 6.0 or later lets you migrate virtual machines between vCenter Server instances.
Migration of virtual machines across vCenter Server systems is helpful in certain VM provisioning cases.
n
Balance workloads across clusters and vCenter Server instances.
n
Elastically expand or shrink capacity across resources in different vCenter Server instances in the
same site or in another geographical area .
n
Move virtual machines between environments that have different purposes, for example, from a
development to production.
n
Move virtual machines to meet different Service Level Agreements (SLAs) regarding storage space,
performance, and so on.
Note During the migration of a virtual machine to another vCenter Server system, the performance data
that has been collected about the virtual machine is lost.
n
Requirements for Migration Between vCenter Server Instances
You can use migration across vCenter Server instances if your system meets certain requirements.
n
Network Compatibility Checks During vMotion Between vCenter Server Instances
Migration of VMs between vCenter Server instances moves VMs to new networks. The migration
process performs checks to verify that the source and destination networks are similar.
n
MAC Address Management During Migration Between vCenter Server Systems
When you move a virtual machine between vCenter Server instances, the environment specifically
handles MAC address migration to avoid address duplication and loss of data in the network.
Requirements for Migration Between vCenter Server Instances
You can use migration across vCenter Server instances if your system meets certain requirements.
