A sparse root zone on an Oracle Solaris 10 system is converted by the system to a whole root model for the solaris10 branded zone migration. A sparse root zone must be in the ready state on the source system before the V2V process occurs. This will mount any inherited-pkg-dir resources before the archive is created. See Zones Overview in System Administration Guide: Oracle Solaris Containers-Resource Management and Oracle Solaris Zones in the Oracle Solaris 10 version of this guide for more information on these concepts.
The zone's brand will be changed as part of the process.
