Any pointers for either software?

I can't speak to Eudora. But for Thunderbird, once a week I back up
my profile from my Windows 7 workhorse and restore it (as files,
using Robocopy /MIR /XJ) to my Windows 8 laptop, so I know that
works. I have some mails stored locally and some stored on the
server, and both types are accessible on the laptop exactly as on the
workhorse. My options, identities, server info, and address book all
come across without a problem.
