Hi Folks,

Firewall is in HA pair, Active - standby mode.

I can see no issue in upgrading directly. Does anyone have any inputs on this please?

    On GEN6-1417 it was found that there was reduction in the TCP receiver window & congestion window on DataPlane causing this issue which had been fixed on

    GEN6-1803 is still being investigated by the engineering team at this moment.
