Id like to know which is the best practice to upgrade CA SSO from 12.52 to 12.8 in a complex scenario with multiple policy server ?
At first glance, as my colleague mention, you might consider a parallel upgrade, as it permits to upgrade most of the components progressively. But in order to study your current architecture and in order to insure you choose the best way, we strongly suggest you to get in touch with CA Services.
