THanks for your reply.
Just a few clarifications:
1. did u shutdown the 10g ASM and db instances and the crs before u
started the upgrade? Asking because, when I tried to run the
runInstaller from 11g grid installation location it complained during
configuration of SCAN that the vip is already assigned. But when I
stopped the 10g CRS it did not complian and proceeded
2. will running runInstaller from grid installation directory upgrade
both COS and ASM?...while starting runInstaller, it automatically
selects the option "upgrdae grid infrastructure", does it mean both
CRS and ASM?
Thanks
