Upgradation of Enterprise Manager 13cR1 to 13cR2 Environment Details:- OS: RHEL 6.4 EM repository DBVersion:12.1.0.2.0 EM Version:13.1.0.0.0 Target DB Version:12.1.0.2.0 Note:- Please confirm the procedure in a testenvironmentbefore performing intothe Production. Steps to perform before the Upgradation:- Checkthe status of OMS and agentservices,alsotake a note of details(assignedportsfordifferent componets,hostname etc)  ./emctl statusoms(omsstatus)  ./emctl statusoms –details(omsdetails)  ./emctl statusagent (agentstatus) Copythe EMKey fromthe currentOMS home to the repositorywhichismandatory,otherwise upgradationwill fail inthe middle.Butdon’tforgettodeletethatEMKeyafterthe upgradation otherwise itremainunsecured.Followthe below commandstocopythe EMKey:-  ./emctl statusemkey(emkeystatus)  ./emctl configemkey –copy_to_repos(copythe emkeytothe repositorydatabase)  ./emctl configemkey –remove_from_repos (removethe emkeyfromrepositorydatabase – use after completionofthe upgradation only) Stop services for OMS, agent using the below commands:-  ./emctl stop oms-all(stopoms)
