I am preparing to upgrade OEM13c(13.2) to 13.3. It is a single-OMS that runs on RHEL7. According to knowledgebase document 2418352.1, you should install software binaries of version 13.3 in a separate home and run "ConfigureGC.sh" script from the new home to perform the upgrade.
Are the knowledgebase document and chapter 4 of Cloud control upgrade guide 13.3.1 is enough for successful upgrade? Please share your experiences, known issues and best practices for a successful upgrade.
Thanks in advance,
