Currently we are using OMS10g (10.2.0.5 oms and db) single node. We are planning to install EM12c on a 2 node cluster VM ware/LINUX .
Could you please let me know what will be the steps using 2 system upgrade.

Thanks Sharma for responding. I am looking documentation if my new OMS want to be on a 2 node RAC. Any idea ?
