Hello,

I'm currently working in version 8.3 and looking for a way to push historical tag values.

Here’s what I’ve found so far:  
The history management system has been redesigned and moved into a separate module called **"historian"** , and as a result, the **HistoryManager** has been removed.

Currently, in version 8.1, I access **storeHistory** from the **HistoryManager** in order to push tag history values:  
`gatewayContext.getHistoryManager().storeHistory(...)`

According to the documentation for `system.tag.storeTagHistory`, it now seems that we should use `system.historian.storeDataPoints` instead.

`system.historian.storeDataPoints` relies on the **storeAtomicPoints** function from **HistorianManagerImpl**.

It's possible to retrieve the instance of **HistorianManagerImpl** using the **getHistorianManager** method from **HistorianGatewayHook**.

Is there a cleaner and more straightforward way to push historical tag values (ideally without relying on reflection or accessing the ScriptManager)?

As you noted, storing Historian data has been moved into the Historian module rather than coupled with the Store & Forward system (old `HistoryManager`, now called `StoreAndForwardManager`) for storage.

The most correct method would be to grab the Historian's `StorageEngine` using `HistorianManager.get(gatewayContext).getStorageEngine(historianName)`, and then to store `AtomicPoints` through `StorageEngine::storeAtomic`. Creating atomic points can be done using `DataPointFactory::createAtomicPoint`.

You shouldn't need to use Reflection. New Historian SDK [dependencies](https://forum.inductiveautomation.com/t/8-3-early-access-sdk-dependencies/93760) will be available on 7/29 that will expose `historian-gateway` and `historian-common`. Currently only `historian-gateway` is exposed through the `historian` artifact (which is now renamed to match).
