[Pdns-users] Is the update protocol between supermaster and superslave pdnsversion agnostic?

Hi :)

I have a setup with pretty old pdns servers (4.2).

One hidden master that serves a number of internet-facing authorative
servers which act as superslaves.

I want to upgrade the lot to the latest version, but preferably without
any downtime.

One way to do that (hopefuly) is to upgrade each internet facing
superslave over a period of time, and upgrade the hidden master as the
last one.

This will only work if the updates from the hidden master to the
superslaves are also recognized and processed as usual , even when de
superslaves run on a recent version (> 4.2) and the hidden master does

Is this the case?

Thank you for your time.
