To simplify the HA set up, configure the Panorama
appliances in HA after you purchase Prisma Access and
Strata Logging Service auth codes and components and associate the serial number of
the primary Panorama appliance on which you plan to install the
Cloud Services plugin with the auth codes, but before you
Activate and Install Panorama Managed Prisma Access. However,
you can also use this process to configure existing Panorama appliances
that already have the plugin installed.
