Connecting v23 and v24 historians via Remote Historian View
We currently have two Canary servers, one v23 and one v24.
Is it supported to set up Remote Historian Views on each server so that the Axiom instance on each can access the Views from the other?
Or, if instead v24 Axiom were installed on a separate standalone server could it talk to both the v23 and v24 historians?
I'm trying to understand the Access, Token, Historian, and Identity configs that would be required to enable this.

Hi ,
The way in which a remote Historian is added to a Views service has changed from v23 to v24. In v24, the Views service needs configured with an API token which needs mapped to a Canary user who would need to reside on the Historian access control list.

It is not possible to link a v23 Historian to a v24 Views service, or vice versa. They would both need to be on the same version. Similarly, a v24 Axiom would not be able to connect to a v23 Historian.
