IAM 11gr2 PS3 upgrade from a single domain topology with OAM/OIM/OAAM Advanced integration
In our current environment, we are on IAM 11.1.2.2 with a single domain topology and we have OAM/OIM/OAAM native integration and OIM/OUD LDAP SYNC in place .
Now, we are upgrading to IAM 11.1.2.3. However, ps3 upgrade only supports split domain topology. So our first priority is to re-create using two domains (access and identity) in new servers, move transaction data from OIM, OAAM and OUD to the new environment. I am wondering has anyone done this in their own environment. Especially any document on moving those transaction data.
Official t2p document using rman to move the database instance however, our database instance is shared by multiple applications besides IAM and using the data pump to clone data runs into some data inconsistency issue.
