Ignition seeing Windowviewer tags

My company is in the process of changing from Wonderware to Ignition.
Windowviewer has a built in IO server and different windowviewer apps are able to access tags on different apps. Is it possible for Ignition to access WW tags?

If WW’s IO server can act as an OPC Classic or OPC UA server then it should be pretty straightforward: just add an OPC connection in Ignition to the WW server.
