Today I'd like to share my presentation on upgrading Oracle SOA Suite from 11g to 12c. It contains information on how the product evolved the last couple of years. It also explains different upgrade strategies, the difference between in-flight upgrade and migration, important pre-upgrade tasks, the upgrade steps itself and post-upgrade steps.
Additionally it lists the experiences and upgrade results that we've
achieved in two different scenarios: in-flight upgrade as well as
migration.
