What kinds of application test do I need to do before database major version upgrade go live?
Hello,
If I choose application is upgraded on all certified Oracle and OS environment on database server and all application client servers ,do I still need to do a complete functional testing before upgrade my database to a newer major version like from 10G to 11G? End user testing is very time consuming. Can I just do a stress test(performance testing) in the test environment and do not do any functional testing at all? How about if I only upgrade my database to a minor version like from 10.2.0.4 to 10.2.0.5? Do I need a functional testing for my application? My
