Inductive Automation Ignition Manual

What is the best way to directly connect Ignition 8.1 to a Wonderware Historian (WWH) so our engineers and technicians can drag and drop tags from WWH and view historical data. We have a firmly entrenched Wonderware System Platform installation and don’t want to move all that to Ignition - although that might not be a bad idea. I’ve seen several posts about migration but that isn’t what I’m looking for. We want to Ignition to co-exist with WWH and use it, not the internal Ignition historian. We don’t want to rebuild our data acquisition and historian infrastructure. We do want to use Ignition for building mobile screens in Perspective. Any advice?

Inductive Automation. Quite the same Wikipedia. The Ignition category is where you can make posts specific to Ignition by Inductive Automation. The Modbus Driver module allows the Ignition OPC-UA server to communicate with any device that supports the Modbus protocol, that is, the Modbus TCP and Modbus RTU over TCP protocols. The Modbus Driver module can connect directly to devices that support Ethernet communications or it can also connect to Modbus devices through a Gateway device.

I’m an absolute noob - been using Ignition about a week now, so this could be something I should already know, so sorry about that. I’m really trying to compare/evaluate how to access WWH: SQL JDBC? OPC-UA? OPC-HDA?
