After much wrangling and trial and error; I finally figured out how to migrate my old Thunderbird e-mails from Windows XP over to Vista.
It was confusing; and I probably made it harder than it had to be; and I am definitely not the computer genius. But I did get it done; and I am happy as there were a lot of e-mails that are important to me, such as the instruictions for ftp'ing to my Website and things of that nature.
Life would not have been over if I had not been successful in migrating the e-mail over; but it is nice that I still have them for reference now. I think I'm going to take some time to go through all of them and print the more important ones out.
It is also working out quite nicely using my old hard drive as an external one on the new computer. It's a nice repository for old documents, doc files and pdf files; such as all my old K9YA Telegraph issues (which I have also burned to CD for posterity).
