If we place a TASKalfa product replacing a Konica machine can we still use the Unity software for Document Management?

I hadn't heard of 'Unity' before, so I took a look.

The only documentation they showed for it was an OmniPage Pro manual, PaperPort Manual and PaperPort Desktop Delivery Manual.

If that's all it is it will work with anything scan to file or scan to smb from what I can tell.
The PaperPort Desktop Delivery utility watches folders and processes workflows.
