Thank you for the response.
I am specifically looking for a stable version in 9.6x... As per our process, we usually dont go to very new version and usually N-1. I was planning to go with 9.6P7 but its just less than a month old.
I have procured a new AFF8040 and its inbuilt with 9.6 and our existing cluster is 9.5P7. So we need to upgrade to 9.6 as minimum for adding the new one to cluster.
So if you can suggest one stable version in 9.6x will be fine.
