Local zones on Solaris are like Docker containers, while the Solaris global zone is like the Docker engine itself.

How do I migrate to LDOM?

LDOM live migration basics explained

1. Phase 1 : Pre-checks. In this phase the source machine does pre-checks on the target system to ensure that the migration will succeed.
2. Phase 2 : Target LDOM creation.
3. Phase 3 : Run time state transfer.
4. Phase 4 : Source domain suspension.
5. Phase 5 : Hand-off.

What is Solaris Zone?
