What is the best strategy for moving to a new OMS
I currently have my OMS as follows Enterprise Manager 12.1.0.1 on Oracle 11.2.01 32bit on Windows 2008R2. I am trying what is the least painful way to migrate my agents, hosts, instances etc to a new OMS. This new OMS would be on Enterprise Manager 12.1.0.4, Oracle 11.2.04 64 bit running on Redhat 6.5.
I believe there are two methods I could use in doing this. I could take the upgrade route. Something like below
METHOD 1
Backup current OMS environment
Stop OMS
Install Oracle 11.2.01 64 bit on my new OS ( I am unsure if this should be 32 bit or 64bit?)
Export data from old OMS import in new OMS
