Hi Peter,
I opened an SR on the same issue. Running a mixed cluster with different
versions of the same OS release is supported for the duration of the
rolling upgrade (i.e. hours, not days).
I'd make sure to test it before.

We've got a 4 node RAC 11gR1 on Linux 4.7 with ASM. We need to bring
the latest patches into the OS and I was wondering what the best
practice would be. I realize that we could do a rolling patch if we
were patching CRS or the databases but can that be done for the OS?
Would it be better (Safer?) to shutdown the whole RAC and do the OS
patch to one node at a time or can we leave 3 nodes up while patching one?
