Introduction


This chapter focuses on various options available to upgrade Enterprise Manager 11g to Oracle Enterprise Manager 12c (OEM 12c).

Upgrading the OEM is a complex activity as it involves updating the underlying software and configurations in different files and possibly residing on various hosts.

There are key challenges of upgrading the OEM environment with minimal downtime. In order to circumvent these challenges, Oracle has provided a few options to be chosen based on user requirements.

This chapter provides a step-by-step process to be followed to upgrade the OEM 11g release to OEM 12c for two types of upgrade approaches such as the 1-system upgrade approach and the 2-system upgrade approach.

Please note that a direct upgrade to OEM 12c is possible from OEM Version 10.2.0.5 or 11.1.0.0. In the following recipes, we have upgraded OEM 11g to OEM 12c.
