For a migration to occur, both the source and target machines must be running compatible software, as follows:
The hypervisor on both the source and target machines must have a compatible version of firmware installed. See Required Software to Enable Oracle VM Server for SPARC 2.0 Features in Oracle VM Server for SPARC 2.0 Release Notes.
A compatible version of the Logical Domains Manager must be running on both machines.
Note - The migration feature was first released with the Logical Domains 1.1 software and corresponding firmware. For information about the latest firmware for your platform, see the Oracle VM Server for SPARC 2.0 Release Notes.
