I've had to reset some progression statuses/channels for a few programs in various programs. In order to do this, I removed program members, removed trigger campaign progression steps, changed channels, batched in the new progressions, etc. This is best practice (I think - correct me if I'm wrong).
Unfortunately, this erases the acquisition program and some of the leads were acquired by the program and some were not. I did not realize this would happen or I would have exported the list of acquired members before removing them from the program so I could manually change acquisition program of those leads back. But they're gone now.
How can I tell which should be acquired by? I suppose I could take a stab in the dark and just say anyone who is now blank should be acquired by that program, but there must be a better way?
