Poll Question: Did you upgrade to 12c and, if so, how?
Oracle has provided several pathways to upgrade from 10.2.0.5 or 11.1.0.1 to 12.1.0.1 or 12.1.0.2:
1) 1-System (12c OMS on same host as prior OMS, all agents upgraded at once, original repository upgraded)
2) 2-System (12c OMS on a different host than prior OMS, gradual agent upgrade possible, copy of repository upgraded)
3) 1-System, different host (12c OMS on a different host than prior OMS, all agents upgraded at once, original repository upgraded)
4) Transition through parallel (old and 12c) EM systems operation without need for data history preservation
Which did you use or have you decided not to upgrade yet?
