not 11g specific, but probably worth a read:

Before and After the Upgrade," by Roger Schrag (February 2005).

Obligatory reference to the Oracle 11g R1 Database Server Upgrade
Depending upon what killer features in 11g you want to leverage vs.
level of risk that you're willing to assume, you might just decide to
upgrade to 10g R2 and hold off on migrating to 11g R1 until after
you've tested, submitted your bugfixes and awaited the availability of
the fixes in a patchset or one-off patch.
10.1.0.2 (base release) wasn't ready for me until after the 10.1.0.4
patchset (10 g R1 patchset2) was applied.
10.2.0.3 (10g R2 patchset 2) with the October Critical Patch Update is
working pretty well for me.
Maybe you'll get lucky with the 188.8.131.52 base release.
Quite a few bugs that are fixed in the upcoming 10.2.0.4 patchset are
also fixed in 184.108.40.206.
Check the known issues doc up on Metalink.
