I remember seeing/hearing that the gateway network connections between 8.3 and 8.1 gateways will continue to work. I can't find a source for that. Is it true or wishful thinking on my part? TIA.

8.1 and 8.3 will continue to interoperate, but 8.3 gateways will not be able to interact with 7.9 gateways, or vice versa.

EDIT:  
As an addenda to this - you will need to _opt in_ to Java serialization for gateway network messages for 8.3 gateways to be able to communicate with 8.1. Java serialization is an inherently less-secure protocol that's been frequently used as a part of "exploit chains" for Java services, so we're discouraging/eliminating its usage as much as possible in Ignition, but for backwards compatibility there are still scenarios where it's required.

Just to add since this post will likely be seen: there are some features that are expected to not work between 8.1 and 8.3 gateways. For example, you cannot edit an 8.3 gateway's tags from an 8.1 gateway via a remote tag provider.

See the [upgrade guide](https://docs.inductiveautomation.com/docs/8.3/getting-started/installing-and-upgrading/ignition-8-upgrade-guide/81to83-upgrade-guide#architecture-considerations) for more details and other scenarios where an 8.3 \<--\> 8.1 gateway network connection might not support every feature.
