cluvfy stage -pre crsinst -upgrade -n db1,db2 -rolling -src_crshome /oracle/app/11.2.0/grid -dest_crshome /oracle/app/grid/126.96.36.199/grid -dest_version 188.8.131.52.0 worked for me from the cluster verify downloaded/bin... Than you for your suggestion.
I have resolved one other cluvfy failure was something ntp related... Only PATCH 9413827 is missing, any suggestion please? Do I need to apply this patch directly or some other PSU which will cover this patch?
