I have an oracle 9.2.0.6 running on sun solaris 64-bit. I am trying to upgrade it to 9.2.0.7, and then on top of 9.2.0.7, need to install the CPU Apr2006 Patch.

Does anyone have a tested approach to this and if so, can you provide me the steps. Or else a metalink docId or notes will also suffice

Also has anyone upgraded to 9.2.0.8 ? Are there any significant differences between the 9.2.0.7 and 9.2.0.8 patches ?
