Certain requirements and restrictions are imposed on the domain to be migrated, the source machine, and the target machine when you attempt to migrate an active domain. For more information, see Domain Migration Restrictions in Oracle VM Server for SPARC 22.214.171.124, 3.1.1, and 3.1 Release Notes .
A domain “loses time” during the migration process. To mitigate this time-loss issue, synchronize the domain to be migrated with an external time source, such as a Network Time Protocol (NTP) server. When you configure a domain as an NTP client, the domain's date and time are corrected shortly after the migration completes.
To configure a domain as an Oracle Solaris 10 NTP client, see Managing Network Time Protocol (Tasks) in System Administration Guide: Network Services . To configure a domain as an Oracle Solaris 11 NTP client, see Managing Network Time Protocol (Tasks) in Introduction to Oracle Solaris 11 Network Services .
