Only a few domain migration restrictions apply to a bound or inactive domain because such domains are not executing at the time of the migration.
The migration of a bound domain requires that the target machine is able to satisfy the CPU, memory, and I/O constraints of the domain to be migrated. If these constraints cannot be met, the migration will fail.
The migration of an inactive domain does not have such requirements. However, the target machine must satisfy the migrated domain's constraints when a bind is later attempted, or the domain binding will fail.
You can migrate a bound or inactive domain between machines that run different processor types and machines that run at different frequencies.
The Oracle Solaris OS image in the domain to be migrated must support the processor type on the target machine.
For an inactive domain, no checks are performed of the virtual I/O (VIO) constraints. So, the VIO servers do not need to exist for the migration to succeed. As with any inactive domain, the VIO servers must exist and be available at the time the domain is bound.
You cannot perform a domain migration on an I/O domain that is configured with PCIe endpoint devices.
For information about the direct I/O (DIO) feature, see Assigning PCIe Endpoint Devices.
