Convai V3/V4 compatibility issue after moving project to another PC

What happened?

Hi, I’m working on a project in Unreal Engine 5.3.2 that uses Convai and MetaHuman.

The project was originally created and working correctly on my previous computer. I recently moved the project to a new computer, installed Unreal Engine 5.3.2, and opened the same project there. After installing the newer Convai plugin (V4), I started getting the message that ConvaiBaseCharacter / ConvaiBasePlayer is deprecated.

My existing MetaHuman and First Person Player were already set up with Convai, and the project worked correctly before moving it to the new computer. I don’t know exactly which Convai 3.x version was installed on the original computer.

I’m trying to determine the safest way to restore the project without rebuilding everything from scratch.

Could someone please advise:

  1. How can I find out which older Convai plugin version the original project was using?
  2. If I download the compatible V3 version from the Convai GitHub releases and put the Convai folder into the project’s Plugins folder, should the existing project work again?
  3. Should I completely remove/disable Convai V4 first?
  4. Would it be better to keep the existing MetaHuman and restore the old plugin version, or should I import/create a new MetaHuman and set it up again using Convai V4?
  5. Is there anything else I should check when moving a Convai project from one computer to another?

I would really like to preserve the existing setup because I already have several dialogue triggers and `Invoke
