I don't know a thing about this, whether it'll work or not. I
would suggest backing up all materials before attempting anything fancy.

FWIW, I've used (an earlier version of) this software to import my
(exported) email from Windows Mail into Thunderbird. Worked fine.

For that, I'd need the old system to be running, so I could tell it to
do the export.

Not neccessarily. You export from a Thunderbird profile. If you can
recover the profile - i.e. a set of folders/files - from the old disk,
you can restore that profile to another system - any system, i.e. also
the 'new' system - and do the export there.

Thanks all; recipient delighted to have old emails back (back to 2008!).

could pass on - I'm unlikely to visit again soon.)]

I found profile switching in TB (which I don't use myself) very
counter-intuitive - in particular the '-p' "profile manager", which to
me was a dead loss (I eventually got the old emails back by '-profile
explicit path name').
