This document describes in detail the Steps for Upgrading to Enterprise Manager 12c R2 using Two-System Method from a 10.2.0.5 / 188.8.131.52 Grid Control. This approach enables you to install Enterprise Manager Cloud Control on a host that is different from the host where your existing Enterprise Manager system is running. This approach does not upgrade the Management Repository in the existing database, but upgrades the one in the backed up database, thus enabling two Enterprise Manager systems to exist. Since a new Enterprise Manager system co-exists with the old one, there is no or near zero downtime involved.
