New Installation Directory and Ports, Same Hosts, Cloned Database
Benefits: Safer than first scenario; rollback is much simpler. Downtime is less than first and second scenarios; can migrate gradually while old installation continues to operate. Can fully automate using custom composite templates.
Cautions: Preparation for migration is more complex than first and second scenarios. Requires double disk space because old installation is still present. Must change endpoints to reflect new ports. Must adjust third-party tooling to new installation.
