Table 111. Network Limits for Migration with vMotion
Operation ESXi Version Network Type Maximum Cost
vMotion 5.0, 5.1, 5.5, 6.0 1GigE 4
vMotion 5.0, 5.1, 5.5, 6.0 10GigE 8
Datastore Limits
Datastore limits apply to migrations with vMotion and with Storage vMotion. A migration with vMotion
has a resource cost of 1 against the shared virtual machine's datastore. A migration with Storage vMotion
has a resource cost of 1 against the source datastore and 1 against the destination datastore.

vMotion 5.0, 5.1, 5.5, 6.0 128 1
Storage vMotion 5.0, 5.1, 5.5, 6.0 128 16
Host Limits
Host limits apply to migrations with vMotion, Storage vMotion, and other provisioning operations such as
cloning, deployment, and cold migration. All hosts have a maximum cost per host of 8. For example, on an
ESXi 5.0 host, you can perform 2 Storage vMotion operations, or 1 Storage vMotion and 4 vMotion
operations.

About Migration Compatibility Checks
During migration, the Migrate Virtual Machine wizard checks the destination host for compatibility with
the migrating virtual machine using various criteria.
When you select a host or a cluster, the Compatibility panel at the boom of the Migrate Virtual Machine
wizard displays information about the compatibility of the selected host or cluster with the virtual machine’s
conguration.
Compatibility Check Results
If the virtual machine is compatible, the panel displays the message Compatibility checks succeeded. If the
virtual machine is not compatible with either the host’s or clusters congured networks or datastores, the
compatibility window might display both warnings and errors:
n
Warning messages do not disable migration. Often the migration is justied and you can continue with
the migration despite the warnings.
