I know that on the older units running LH2 you can not network them with a LH3 Axiom or eS unit.
I have heard that some data can be shared between the units over seatalk.

Is there any chance of getting the waypoints to transfer between units.
It would be nice to be able to mark spots on the Axiom, then use a unit with LH2 on the front to fish the marked spots!!

Welcome to the Raymarine Forum Hickory Legend,

Unfortunately, the feature which you have inquired about would require that a pair of compatible MFDs be interfaced via Ethernet communications. Waypoint/route synchronization/sharing presently requires Ethernet communications between the MFDs. In systems such as you have described, it would be recommended that all MFDs be running LightHouse II v19.03 software. That said, a feature request will be logged to consider such capability for a future LH II software update (none currently planned) and LH 3 software update, as both operating systems would need to include such a feature.
