In step 2 it is mentioned that "take the backup of the PROD Database". that makes me confuse. I can'tYou need the backup to restore in case there is an issue during the upgrade.
If the Step 3 is not going to touch any thing on the database why would need the backup of the database.
And I have two brand new servers for R12. My Question is while installing the R12.1.1, it is asking for the database node details---- Can I give my PROD Database node details, while the PROD db is still using by the 220.127.116.11 application.Yes (as long as the Database host is accessible by the new application tier nodes).
I can take the backup just before starting the real upgrade.Correct, but it is recommended you follow the steps in the doc (see below for what update is done by Rapid Install as this stage).
Step 3 : I do observed that "Create File system" is running Autoconfig at the end of installation,does it update my database.Yes.
I am sorry if i am asking same question.Never be sorry.
Q1: In production environment can i apply these preinstall mode patches before the down time?Could you please mention the list of the patches?
Q2: Do I need to merge there drivers with the upgrade driver i.e u6678700.drv? Base for this questions is I did applied in preinstall mode only, I am not able to see them as applied patches from ad_applied_patches. Am I missing something here?You can merge the preinstall patches with the main upgrade patch driver. However, please mention those patches as requested above to confirm.
The below are the preinstall patches I have applied in the first cycle to avoid the bugs while applying the 6678700 driverI believe you have gone through the patches README files and it all instructs to apply those patches in preinstall mode.

Still I got the bellow errors, and found few more patches to be appliedNot sure what do you mean here -- Run AutoPatch in pre-install mode only if the patch readme instructs you to do so.
I which case do I need to merge these patches with 6678700?
I wish install these patches in preinstall mode so that I can save some down time. If I install these patches in preinstall mode how come I am not able to see those patches in ad_bugs/ad_applied_patches. Do I need to merge those patches to 6678700 even though I applied in advance with preinstall option.No.
