OEL5.3, Oracle 11.1.0.7 and PTools patches

My lab is becoming out of date, built more than one year ago.
My OS is Oracle Entreprise Linux 4.6, and last week the 5.3 has been released, time to get a newer OS.
My databases are Oracle 10.2.0.4, and now Peopletools 8.49 is supported onto 11.1.0.x for a while, time for change.
Lastly, my Peopletools are 8.49.11, the latest patch is 8.49.18, also time to go further.

It is a lot of work, I'm planning to create a new VM, install all the required binaries (Oracle, Peopletools, Application HRMS, CRM and FSCM) then move the databases to that new VM and upgrade them.

I'll post soon the steps of that migration.

Enjoy,
