Move (100s of) QSOs to a different logbook?

[ei8fdb]

I've been logging my POTA, SOTA activities to separate logbooks (i.e. POTA activations, SOTA activations), but now realise this isn't the best idea. It's common that landmarks; summits parks, beaches etc can be park of multiple programs. E.g. many summits are located in parks.

So now I'd like to move all my POTA, SOTA QSOs into 1 logbook. Ideally I'd like to do this in bulk.

There was a previous question about moving a QSO from a logbook/location (discussion #3078), but the answer provided covered just moving location, not logbook.

Does anyone have any suggestions on how to do this?
