MQTT connection between old version Edge and V8.3 Gateway

I have newly installed ignition gateway V8.3.

The MQTT Engine and Distributor are V5.00 beta 2.

I installed a new ignition edge with MQTT transmission module V5.00 beta 2. It can communicate with the V8.3 Gateway.

But when I tried to connect from an existing installed MQTT transmission module V4.0.15, the edge cannot connect with new V8.3 gateway.

Is it a version compatible issue?

Is there any ignition MQTT module compatible matrix table I can refer to?

Or another question, the edge ignition is V8.1.24, can I upgrade the edge MQTT transmission version to V5.00 beta 2?
