Well you would be well advised to take a backup (especially of the root filesystem) before patching in case it goes wrong.

How do you backup this system now?

I would recommend taking a ufsdump (using fssnap and ufsdump commands) to either a tape drive or over the network via NFS to another system. I would also ensure that you have a copy of the vtoc (virtual table of contents) (using the prtvtoc command). Having that is priceless in the event that recovery is necessary. Once you've done that you have a full copy of your data even if, at this time, you don't know how to restore it.

Once that's done you can apply your required patches and/or Oracle recommended patchset.

NAME
splitdiff - separate out incremental patches SYNOPSIS
splitdiff [-a] [-d] [-p n] [-E] [file] splitdiff {[--help] | [--version]} DESCRIPTION
If you have a patch file composed of several incremental patches, you can use splitdiff to separate them out. You may want to do this in preparation for re-combining them with combinediff(1). The effect of running splitdiff is to separate its input into a set of output files, with no output file patching the same file more than once. OPTIONS
-a Split out every single file-level patch. -d Create file names such as a_b.c.patch for a patch that modifies a/b.c. -p n Strip the first n components of the pathname to aid comparisons. -E Don't use .patch filename extension when writing output files. --help Display a short usage message. --version Display the version number of splitdiff.
