Same Installation Directory, Hosts, and Ports; Live Database
Command Central renames the old product installation directory, then uses the old directory name for the new product installation.
Benefits: Simple; similar to overinstall in that all paths, hosts, and ports remain the same. Can fully automate using custom composite templates.
Cautions: Risky; rollback is complicated. Significant downtime. Must back up live databases; use of cloned databases is not supported. Requires double disk space because old installation is still present. Requires extensive automated testing before production environments can be migrated.
Command Central provides templates you can use for this scenario on GitHub at https://github.com/SoftwareAG/sagdevops-templates/tree/master/templates/
