This chapter describes an example consolidation of existing systems that contain some virtual elements. By implementing this consolidation, you would accomplish the following goals:
Consolidate existing Oracle Solaris 11, Oracle Solaris 10, and Solaris 8 servers onto a single SPARC server.
Increase hardware and software efficiency and streamline system maintenance through the exclusive use of virtual environments.
Run applications with different SRUs or update schedules on the same server by using Oracle Solaris kernel zones.
Maintain isolation and perform application monitoring by running each application in its own zone or guest domain.

The following migrations and consolidations are performed:
Two Oracle Solaris 11.1 systems, sol11-sys1 and sol11-sys2, run in the Oracle Solaris 11.3 guest domains ldg1 and ldg4. The guest domains ldg1 and ldg4 host applications in native Oracle Solaris zones and kernel zones.
The Solaris 8 system sol8-sys1 runs on an Oracle Solaris 10 guest domain ldg3.
Two Solaris 8 systems, sol8-sys2 and sol8-sys3, are migrated onto the solaris8 zones in an Oracle Solaris 10 guest domain ldg2.
The high-level tasks to perform the consolidation into virtual environments are described in the following sections.
