If I had to do migration again, I'd do it the same way as before: I'd
copy from the source client to an IMAP account, and then from the IMAP
to Claws. Or, in my case, I didn't do the last step -- I just kept all
my email on my local IMAP server, and that IMAP server's Maildir
structure is what I back up.

I tried for a few weeks to export and import from files, and man, it
was very bad news. Only after I committed to the IMAP middleman did
things go well.

The whole process is described here:
