How to upgrade to 9.2.0.7 and apply CPUJan together

I want to upgrade our DB from 9.2.0.4 to 9.2.0.7. Since the 9.2.0.7 patchset does NOT cover the latest CPU a.k.a Critical Patch Upgrade) in Oct.2005 and Jan.2006, I will have to apply all of them. There are 2 ways to follow:

1. Upgrade software level 9.2.0.7 and CPUJan together and then upgrade databases;
2. Upgrade software for 9.2.0.7 and upgrade databases; then apply patch CPUJan and post-installation work on databases.

I personally like to Option 1 since it will save me time. But I don't have document to back it up. I have tried to search the documents on Metalink. But I found nothing so far.

Have anyone here done the above work or found any related documents?

If you have support with Oracle, then they can guide you.

Do you have it?
