So, upgrade to 12.1.1/12.1.3 then upgrade the 10.1.3 ORACLE_HOME to the latest patchset (10.1.3.5).
Is it OK to upgrade the 10.1.3.4 OH to 10.1.3.5 after we install the R12.1.1 file system but before running the R12.1.1 upgrade driver, so that we could complete the techstack related steps before the actual downtime to save time during the actual upgrade?

Thanks Hussien, Could you please be more specific on the patches that you are talking about? as from the note, patches 8999551,12965674 are opatches and could be applied and we would be having the 12.1.1 file system already just that our data model is still 12.1.1 and 12.1.1 is certified to use 10.1.3.5. So is there anything that I am missing?
